Kenya, Uganda, Tanganyika is the name used to describe the postage stamps issued by the East African Posts Administration between 1935 and 1961 for use in the colonies of Kenya, Uganda, and Tanganyika.

Philatelists usually class the 1921-1927 issues of the East Africa and Uganda Protectorates and Kenya and Uganda under KUT , but the first issues spelling out all the names of the colonies came in 1935, in the form of common commemorative design for the Silver Jubilee of King George V
