Kromosom Y adalah satu daripada dua kromosom penentu jantina (alosom) bagi mamalia, termasuk manusia (yang satu lagi adalah kromosom X). Dalam mamalia, kromosom Y mengandungi gen SRY yang mencetuskan perkembangan testikel jika ada. Kromosom Y manusia terdiri daripada sekitar 50 juta pasangan bes. DNA dalam kromosom Y diturunkan dari bapa kepada anak lelaki, oleh itu analisis Y-DNA boleh digunakan dalam penyelidikan genetik. Dengan perbezaan sebanyak 30% antara manusia dan cimpanzi, kromosom Y adalah antara bahagian yang paling cepat berevolusi dalam genom manusia.[4]
