在篮球运动中，包夹（英语：Double team，double-team，double teaming，double-teaming），又称双人包夹、双人夹击、双人防守，是一种防守战术，意指以两个防守球员，针对单一位进攻球员，进行紧密防守。

与区域联防不同，在包夹战术中，防守球员通常会先被指派去针对某个特定的球员进行防守，这称为人盯人战术（man-to-man）。但是当防守球员无法成功防守某位进攻球员时，另一个防守球员会立即加入防守，形成双人小组，造成包夹。成功的包夹防守，可以阻碍进攻球员的运球及传球，造成进攻球员的失误（turnover），以阻止对方得分。

In basketball, a double team (also double-team, double teaming, or double-teaming) is a defensive alignment in which two defensive players are assigned to guard a single offensive player.

Among basketball strategies in which defenders are assigned to specific players (as opposed to "zone defenses" in which they are assigned to specific regions of the court), each defender is assigned to one offensive player (a "man-to-man" alignment). However, when an offensive player is overwhelming his or her defender, another defender may help out and create a double team. A successful double teaming can greatly impede that offensive player's movement and passing, such that passing him or her the ball frequently results in a turnover. However, because devoting two defenders to a single offensive player leaves another offensive player unguarded, if the offensive player succeeds in both receiving the ball and passing it to that teammate, the teammate's likelihood of making a shot becomes much higher than usual.
