The Oldsmobile 4-4-2 is a muscle car produced by Oldsmobile between the 1964 and 1987 model years. Introduced as an option package for US-sold F-85 and Cutlass models, it became a model in its own right from 1968 to 1971, spawned the Hurst/Olds in 1968, then reverted to an option through the mid-1970s. The name was revived in the 1980s on the rear-wheel drive Cutlass Supreme and early 1990s as an option package for the new front-wheel drive Cutlass Calais.

Muscle car is a description according to the online Merriam-Webster Dictionary in 2022 that came to use in 1966 for "a group of American-made two-door sports coupes with powerful engines designed for high-performance driving." The online Britannica Dictionary described these in 2022 as "an American-made two-door sports car with a powerful engine."
