Doggy style is a sex position in which one participant bends over, crouches on all fours (usually on hands and knees), or lies on their abdomen, for sexual intercourse, other forms of sexual penetration or other sexual activity. Doggy style is a form of rear-entry position, others being the spoons sex position in which the receiving partner lies on their side or the reverse cowgirl sex position. Non-penetrative sex in this position may also be regarded as doggy style.

Between sex partners, the person in the doggy style position is usually passive, while the other partner is active (although sometimes it can be the other way around if the person in doggy position backs up into their partner behind them). Either partner may be the dominant partner or the submissive partner.
