David J. "Hawk" Wolinski (born 1948) is an American keyboardist, songwriter and record producer, probably best known for his work with the funk band Rufus and their lead singer Chaka Khan.

Wolinski grew up in Chicago, Illinois, and in the late 1960s was the keyboard player and lead singer of the band The Males and a member of the bands Shadows of Knight and Bangor Flying Circus. When the latter band broke up he helped form the band Madura, which was produced by fellow Chicagoan James William Guercio. Guercio used Madura in his 1973 film Electra Glide in Blue; Wolinski also had a small acting role.

In the 1960s Wolinski formed a short lived band in Chicago called The Electric Band. They played regularly at a club called The Cellar.
