"Gee, Baby, Ain't I Good to You" (also known as "Gee, Ain't I Good to You") is a jazz standard from 1929. Its music was written by Don Redman (1900–1964), an American composer, bandleader and arranger, and its words by Andy Razaf (1895–1973), an American poet and lyricist. Wikidata gives the key as E-flat major, and the song is classed as jazz.
The original recording was made by McKinney's Cotton Pickers, with Redman directing and a vocal refrain by Donald Redman. It was recorded for Victor on 5 November 1929 and released as a single that year. Later recordings include those by Billie Holiday (1954), Peggy Lee (1956), Ella Fitzgerald and Louis Armstrong (1957), The Coasters (1960), Oscar Peterson (1966) and Ray Charles (1967).
