In Step is the fourth studio album by Stevie Ray Vaughan and Double Trouble released in 1989. The title In Step can be seen as referring to Vaughan's new-found sobriety, following the years of drug and alcohol use that eventually led Vaughan into rehabilitation. It was also Vaughan's final album with Double Trouble. In 1990, he recorded a collaboration album with his brother, Jimmie Vaughan, called Family Style; later that year, Stevie Ray Vaughan died in a helicopter crash.

The album's subject matter incorporates political and social concerns of the time.
