Kurt Koffka (18 March 1886 – 22 November 1941) was a German psychologist. He was one of the founders of Gestalt psychology.

Koffka was born and educated in Berlin and earned his PhD there in 1909 as a student of Carl Stumpf. Koffka also spent one year at the University of Edinburgh in Scotland where learnt English, a skill that later served him well. Koffka worked at the University of Frankfurt when Max Wertheimer arrived in 1910 and invited Koffka to take part as a subject in his research on the phi phenomenon.

Koffka left Frankfurt in 1912 to take a position at the University of Giessen, where he worked for over eleven years. Koffka then travelled to the United States, where he was a visiting professor at Cornell University from 1924 to 1925, and two years later at University of Wisconsin–Madison. Eventually, in 1927, he accepted a position at Smith College in Northampton, Massachusetts, where he remained until his death in 1941.
