网球是一项体育运动，常见的有一对一的单打和二对二的双打，对抗双方隔着球网，用球拍将橡胶制空心球击打至对方场地中，目标是令对方无法将球按规则击回。

网球现在是一项奥运会比赛项目，适合社会各阶层与年龄段人群。现代网球起源于英格兰伯明翰的“草地网球”。1890年，网球比赛规则定型，至今调整不多，仅有的修改包括规定发球者的位置和引入“平分规定”。近来网球大赛引进了电子监控系统和球员挑战规则，使球员有机会用技术手段确定球是否出界。

网球比赛的观众数目众多，四大满贯赛事特别受到关注，包括澳网（硬地）、温网（草地）、法网（红土）和美网（硬地）。

Tennis is a racket sport that can be played individually against a single opponent (singles) or between two teams of two players each (doubles). Each player uses a tennis racket that is strung with cord to strike a hollow rubber ball covered with felt over or around a net and into the opponent's court. The object of the game is to play the ball in such a way that the opponent is not able to play a valid return. The player who is unable to return the ball will not gain a point, while the opposite player will.
