Kalsitriol (bahasa Inggris: 1,25-dihydroxycholecalciferol, 1,25-dihydroxyvitamin D3, 1,25-(OH)2D3) adalah hormon pleitrofik yang merupakan bentuk aktif vitamin D setelah proses konversi oleh ginjal,[1] terhadap kalsidiol yang disekresi oleh hati,[2] dengan katalis berupa enzim sitokrom P450 hidroksilase 1-alfa.[3]

Kalsitriol memiliki sifat anti-proliferatif, pro-apoptotik dan pro-diferensiasi terhadap berbagai jenis sel tubuh, dan sifat anti-kanker, seperti kanker prostat, kanker usus besar,[4] kanker indung telur, kanker payudara, leukimia,[5] oleh kapasitas regulasi terhadap metabolisme kalsium dan fosfat,[6][7] serta modulasi sistem kekebalan dan fungsi sistem saraf pusat.[4]

Kalsitriol akan dikonversi menjadi asam kalsitroat sebelum diekskresi melalui empedu,[8] atau urin.[9]
