Olympic weightlifting, also called Olympic-style weightlifting or weightlifting, is a sport in which participants attempt a maximum weight single lift of a barbell loaded with weight plates. The two lifts competed are the clean and jerk and the snatch.

In comparison with powerlifting which tests limit strength (with or without lifting aids), olympic weightlifting tests ballistic limits (explosive strength) with smaller weights, such that the lifts must be executed faster and with more mobility, because of a greater range of motion during the lifts. However, parts of the lift, especially in the clean and jerk, do test for absolute strength, as power is not an issue in executing that part of the lift.
