Keith Black (June 25, 1926 – May 13, 1991) was an American producer of high performance drag racing engines, often used in Top Fuel and Tractor pulling applications.

Black spent time in the late 1960s with Roland Leong's Hawaiian Top Fuel dragsters, and in the early 1970s with the Plymouth Barracuda Funny Car campaigned by "Big John" Mazmanian.

Black's aluminum engine blocks would dominate the market by the end of the decade.

The engines Keith Black produced were based on the Chrysler 426 Hemi, Chevy Big Block, and Oldsmobile Big Block designs, but cut from virgin aluminum castings and built to the customer's specifications.

Keith Black died from complications due to brain cancer in 1991.
