The fastball is the most common type of pitch thrown by pitchers in baseball and softball. Its distinctive feature is its high speed. "Power pitchers", such as former major leaguers Nolan Ryan and Roger Clemens, relied on the speed, often exceeding , and movement of their fastballs to prevent the ball from being hit. As an alternative to the fastball, pitchers can put more movement on slower thrown balls, or throw them towards the inside or outside of home plate where batters cannot easily reach it.

Fastballs are usually thrown with a backspin so that the Magnus effect creates an upward force on the ball. This causes it to fall less rapidly than expected, and sometimes causes an optical illusion often called a rising fastball. Although it is impossible for a human to throw a baseball fast enough and with enough backspin for the ball to actually rise, to the batter the pitch seems to rise due to the unexpected lack of natural drop on the pitch.
