Burung hantu kelabu besar (Great Gray Owl atau Strix nebulosa) adalah salah satu spesies burung hantu yang pertama kali dideskripsikan oleh Johann Reinhold Forster (seorang naturalis yang mengikuti perjalanan Kapten James Cook pada pelayaran keliling dunia yang kedua) pada 1772.
Nama nebulosa itu diadaptasi dari kata nebulosus yang berarti berkabut (foggy). Burung ini memiliki julukan lain yang cukup banyak: Great Gray Ghost (hantu kelabu besar), Phantom of the north, cinerous owl, spectral owl, lapland owl, spruce owl, bearded owl dan sooty owl. Ia menjadi logo provinsi Manitoba di Kanada.
Burung yang berukuran panjang 61 – 84 cm dan berat 790 – 1454 gram ini aktif di malam hari, termasuk kala senja dan sebelum fajar menyingsing. Ia juga aktif di siang hari, ketika masa bertelur.
Kala musim dingin, burung ini membutuhkan pengerat kecil itu sebanyak sepertiga berat tubuhnya per hari. Sang betina wajib menumpuk cadangan makanan untuk bertahan hidup melampaui bulan-bulan musim panas yang jauh lebih sulit.
Menurut catatan peneliti, si burung yang tinggal di belahan Amerika Utara kerap berpindah mengikuti perpindahan si vole tersebut. Ia sanggup terbang ratusan kilometer mengikuti naik-turunnya populasi mangsa. Namun buat yang hidup di California yang jenis makanannya lebih beragam, cenderung menetap.
Burung hantu kelabu besar dapat mencapai umur 40 tahun, dalam penangkaran. Di habitat alaminya, si burung mati lantaran disebabkan kelaparan. Musuh alaminya, ketika si burung masih remaja, adalah serigala, marten dan Great Horned Owl. Ia tersebar dari Alaska hingga seluruh Kanada, di Pegunungan Rocky bagian utara dan Minnesota bagian utara. Ia juga ditemukan di Eropa dan Asia bagian utara.
