《最终幻想IV》(日语:ファイナルファンタジーIV,英语:Final Fantasy IV,台湾旧译「太空战士IV」)是由史克威爾(今史克威爾艾尼克斯)開發並發行的電子角色扮演遊戲,為最終幻想系列的第四部本傳作品。1991年首發日文的超級任天堂版,後於多個平臺移植或重製。由於《最終幻想II》和《最終幻想III》的初版並未發行日文以外版本,故本作最初在北美發行時取名為「最終幻想II」(Final Fantasy II)以順應當地編號,但後來移植或重製的歐美版本則改回了原標題。
由于卡带容量限制,游戏剧本必须砍为原长的1/4,但时田确保只是去掉“不必要的对话”而非实际剧情元素。随着从FC到超级任天堂画质的提升,天野喜孝可以创作比前作更精美的角色设计,从图像上也已可明显看出人物特征。时田认为减少剧本长度可以加快游戏步调[33][41]。但他也承认故事某些部分“不清晰”,或是“看着没有深度”,这直到后来的移植与重制版才有改善。由于时间和容量限制,游戏放弃了一个想法,即在游戏接近尾声时的一个迷宫中,各个角色可以提升自己能力;该迷宫后来作为月之遗迹收录自Game Boy Advance版游戏中[33]。
英文本地化版《最终幻想IV》沿用了剧情、图像与原声,但开发者为新玩家而显著降低了难度[48]。因容量限制,一些角色的描述和情节背景元素被删除。例如凯恩的背景、与其父亲的关系,以及塞姆斯殖民地球计划的动机都没在游戏中出现[49][與來源不符]。此外其他明显的变化有,去掉了明显有关犹太-基督宗教内容,以及某些潜在让人反感的图形。例如魔法“神圣”改为了“白”(White);所有有关祈祷的内容也都被删除,敏西迪亚的祈祷之塔改名为祝愿之塔(Tower of Wishes)。直接表现死亡的内容也被删除了,尽管几个角色在游戏中仍然显然死亡[50]。修改翻译是依照当时任天堂美国的审查政策[51]。
PlayStation移植版后来与《时空之轮》打包,于2001年以《最终幻想编年史》为名在北美发行;PlayStation版还与《最终幻想V》打包,于2002年以《最终幻想选集》(Final Fantasy Anthology)为名在欧洲和澳洲发行[55]。英文本地化版使用了新翻译,但一些翻译则使用了以前森山薰的翻译,如“You spoony bard!”被保留下来,并获爱好者的喜爱[56]。在PlayStation上做了少许改变的WonderSwan Color重制版于2002年3月28日在日本发行。重制版通过加强细节与调整彩色浓淡,改善了角色的图标与背景[57]。
Game Boy Advance重制版由再次由东星软件移植,发行名称为《最终幻想IV Advance》。游戏由任天堂美国于2005年12月12日在北美发行,史克威尔艾尼克斯于2005年12月15日在日本发行,任天堂于2006年2月23日在澳洲发行,并于2006年6月2日在欧洲发行。游戏于日本发行了一个特别版,其中包括限量版Game Boy Micro,以及一个印有塞西尔和凯恩插画的面板[58]。游戏较WonderSwan移植版更大的改进了图像,并在音乐上做了小修改。英文本地化团队校订了翻译,改善了故事流畅度,并恢复了原版缺少的细节情节[48]。原北美版中删除的内容被重新加入,魔法名改用更接近日文的译名,如将“Bolt2”改为“Thundara”[50]。游戏在试炼之山加入了新洞窟,其中藏有五位角色的强力武器防具,此外还有游戏通关后才能进入的迷宫月之遗迹[48]。
原版游戏WiiVirtual Console服务于2009年8月4日在日本发布,2010年3月8日在北美发布,2010年6月11日在PAL区发布[60]。与日本i-mode手机兼容的强化移植版于2009年5月发行。其保留了Wonderswan Color于Game Boy Color移植版的特性,但将画质提升为后来游戏《月之归还》的水平,并加入了可在游戏完成后可以进入的新“附加迷宫”[61]。
PS版合輯《最終幻想選集》在1999年售出40萬份,成為當年日本第31暢銷的電子遊戲[90]。週刊《Fami通》專家組的六名評論者給遊戲打了54/60分[54]。Game Boy Advance版《最終幻想IV Advance》獲評論者讚揚[67],但一些評論認為遊戲畫面沒有達到當時遊戲良好的質量,特別是相對於《最終幻想V》而言[48][91]。評論稱一些愛好者可能挑剔於新翻譯的某些錯誤[79]。任天堂DS版遊戲在視覺、畫面改變以及新對話上都獲稱讚[92][93][94]。遊戲獲IGN2008年電子遊戲獎之最佳任天堂DS RPG提名[95]。
^Fusoya: Long ago, the world that lay between the Red Planet and the Great Behemoth stood at the verge of destruction, both terrible and complete. The last survivors of that devastation boarded a ship and escaped to the Blue Planet. / Cecil: Blue Planet? / Fusoya: The one that you call home. But your planet was still in the midst of its evolution, you see. And so those travelers created a second moon for the planet, and there they settled into a long and quiet slumber. Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
^King of Baron: This is most unfortunate, but I can place no trust on one who offers none in return. I hereby relieve you of command of the Red Wings. / Cecil: My liege! / King: You will go now to the Valley of Mist instead. There is a task I would have you do. A phantom creature haunts the borders of that land-the Eidolon of Mist. You will slay it and deliver this ring to the village that lies beyond — they will know its meaning. Be gone by first light in the morning! Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.

^Elder: First you must ascend the mountain and trade your dark sword for one of light. Should the hallowed light deem you worthy, you will be made a paladin--a warrior of virtue.

Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
^Cecil: Weren't you planning to go after Golbez?. /Tellah: Yes, but my magic is no match for a man of his strength. I've been searching for the legendary magic of Meteor. It has been long sealed away, and I know not where. But I feel a powerful aura radiating from this place. I believe the spell I seek may well rest within this mountain. Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
^Cecil: What have you done with the king!? / "King of Baron": Would you like to go and see him, that king of yours? You best not mistake me for another Scarmiglione. How one as weak as he came to be crowned an archfiend is something I will never know. Mwa ha ha! / Cecil: Then you're one of them! / "King of Baron": Behold! I am the Drowned King, Cagnazzo--archfiend of water and sworn servant of Golbez! Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.

^Golbez: So, the old man's interference severed my hold over you. No matter. Your purpose is served.

Square Enix. 2008-07-22.
^Cecil: Kain, we've lost the Earth Crystal. Golbez holds all them now. / Kain: No. he holds four. / Rosa: You mean to say there are more? / Cid: Come to think it, I've heard tales of others! You speak of the Dark Crystals? / Kain: I do. / Kain: There is more. He said when all of the Crystals were gathered, the way to the moon would be opened. Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
^Cid: Once you breach surface, I'll seal off that hold for good--with this! / Rosa: No! Not you too! / Cid: I was hoping I'd get to see your kids someday, but, well--someone's got to keep Yang company! You get yourselves back to Baron. Talk to my boys there! / Rydia: But Cid! You'll die! / Cid: And so young, too! Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
^Golbez: Kain...Return to me, my pawn...Deliver to me the Crystal... / Cecil: Golbez! / Cecil: Kain! / Rosa: Don't listen! Resist him! / Kain: It's alright. I...I'm back in control of myself. / Edge: You filthy double-crosser! / Rosa: Kain. What are you doing!? /Golbez: You underestimate the strength of my abilities. I had but slackened your friend's leash, waiting for the proper moment to pull it taut. With this final Crystal, the Tower of Babil will be made complete. Come, Kain. / Cecil: Kain! Don't listen to him! Kain! / Kain: The Crystals are all assembled. We can open the way to the moon at last! Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
^Cecil: And the Lunar Whale, where did it come from? / Fusoya: Ah, the ship...My younger brother Kluya built that vessel long ago, and flew it to the Blue Planet. He took with him several of our secrets, such as the ones employed in your Devil's Road and in airships--a gift to your people. Kluya was fascinated by your planet and wished to know more about it. And while he was there, he fell in love with a woman of your planet. Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
^Fusoya: He thought it fit that we should simply raze all existing life on the Blue Planet and claim it as our own. / Rydia: That's horrible... / Fusoya: Yes. And so I used my powers to force him into hibernation with the others. But as he slept, his will grew stronger and took on a consciousness all its own. It reached out to men with tainted hearts on your planet, twisting them into beings yet darker still. And through them, he began to gather the Crystals. / Cecil: So he was manipulating Golbez! / Edge: Does this guy have a name? / Fusoya: His name is Zemus. The Crystals function as a source of energy you see. I fear he has gathered them in order to activate the interdimenional elevator within the Tower of Babil. With it, he will be able to transport the Giant of Babil to your planet and use it to extinguish all life there.Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
^Golbez: My father... His name was Kluya. / Rosa: That you're Cecil's own... / Edge: Brother!? Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
^Zeromus: I am the wellspring of darkness, fed by Zemus's unbridled hate. I am He who is called Zeromus... I am He who know naught but hate! Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
^Golbez: I cannot return. Not after I have done. And I would very much like to meet my father's people. At least one time. Square Enix. Final Fantasy IV DS. Nintendo DS. Square Enix. 2008-07-22.
