棋钟，是用于围棋、西洋棋及将棋等棋类比赛时的计时工具。通常有代表比赛双方的两个钟与按钮，比赛开始前会将两个钟调至一致的时间（例如2小时）。开始比赛后，一方下棋后按钮，则自己这方的钟会暂停倒数计时，另一方的钟会开始倒数，直到另一方按下按钮，以此控制思考棋路的时间。

A chess clock consists of two adjacent clocks with buttons to stop one clock while starting the other, so that the two clocks never run simultaneously. Chess clocks are used in chess and other two-player games where the players move in turn. The purpose is to keep track of the total time each player takes for their own moves, and ensure that neither player overly delays the game.
