Doris Mary Ann von Kappelhoff (Cincinnati, 3 april 1922) is een Amerikaans zangeres, actrice en dierenactiviste. Ze werd bekend onder de artiestennaam Doris Day.

Doris Day heeft haar grote populariteit te danken aan haar rollen in romantische komedies:

Pajama Game - 1957;
Pillow Talk - 1959;
The thrill of it all - 1963;
Send me no flowers - 1964;
Do not disturb - 1965
en een aantal succesvolle filmliedjes:

It's magic uit Romance on the high seas - 1948;
Secret love uit Calamity Jane - 1953;
Que sera, sera uit Alfred Hitchcocks The man who knew too much - 1956.
In 1975 verschenen haar memoires onder de titel Doris Day: her own story.

Van 1968 tot 1973 speelde ze in de televisieserie The Doris Day Show, die in de jaren zeventig ook in Nederland op het scherm kwam.
