缠斗（又名：空中格斗）是描述两架军用飞机在近距离战斗的型态，大多数的场合是描述两架或者多架战斗飞机企图击落或者威胁对方的空中战斗作为。缠斗的英文原文为Dogfight，有直接翻译为狗斗，此名词的最早运用可能为于第一次世界大战时期，两架军用飞机为了进入对方尾部的范围，这种过程看起来很像两条狗在互相追逐对方的尾巴。

缠斗衍生的战术与训练开始自第一次世界大战，到了第二次世界大战的时候发展至巅峰。虽然进入了飞弹时代，许多空中战争利用雷达的协助，在相当远的距离就能够发现，并且攻击其他军用飞机，缠斗仍然是一项很重要的训练项目，而且缠斗在意义上涵盖的作战距离也比较以前更高。

A dogfight, or dog fight, is an aerial battle between fighter aircraft, conducted at close range. Dogfighting first appeared during World War I, shortly after the invention of the airplane. Until at least 1992, it was a component in every major war, despite beliefs after World War II that increasingly greater speeds and longer range weapons would make dogfighting obsolete. Modern terminology for air-to-air combat is air combat maneuvering (ACM), which refers to tactical situations requiring the use of individual basic fighter maneuvers (BFM) to attack or evade one or more opponents. This differs from aerial warfare, which deals with the strategy involved in planning and executing various missions.
