Bernard "Buddy" Rich (September 30, 1917 – April 2, 1987) was an American jazz drummer and bandleader. Rich was billed as "the world's greatest drummer" and was known for his virtuosic technique, power, groove, and speed.

Rich's technique has been one of the most standardized and coveted in drumming. His dexterity, speed and smooth execution are considered "holy grails" of drum technique. While Rich typically held his sticks using traditional grip, he was also a skilled "match grip" player, and was one of few drummers to master the one-handed roll on both hands. Some of his more spectacular moves are crossover riffs, where he would criss-cross his arms from one drum to another, sometimes over the arm, and even under the arm at great speed.

He often used contrasting techniques to keep long drum solos from getting mundane. Aside from his energetic explosive displays, he would go into quieter passages. One passage he would use in most solos starts with a simple single-stroke roll on the snare picking up speed and power, then slowly moving his sticks closer to the rim as he gets quieter and then eventually playing on just the rim itself while still maintaining speed. Then he would reverse the effect and slowly move towards the center of the snare while increasing power.
