A slide rail assembly includes a first rail, a second rail, a first engagement element, and a second engagement element. The first rail includes a first blocking part. The second rail is movably connected to the first rail. The first and second engagement elements are connected to the second rail. When the second rail moves relative to the first rail toward a first position, the first engagement element abuts against the blocking part of the first rail. When the first engagement element is operatively detached from the blocking part of the first rail, the second rail to is able to move relative to the first rail toward a second position from the first position. When the second rail is located at the second position, at least part of the second engagement element is adjacent to the blocking part of the first rail.
