直线竞速赛（Drag racing），是汽车场地比赛项目之一，比赛依不同的车型以及发动机的容积分为12-14级别，在两条并列长1,500米，各宽15米的直线柏油跑道上进行，在两辆车之间进行，采取定点发车方式完成一定距离的比赛。公认的标准距离为1/4英（402.336米）或1/8英里（201.168 米）。

Drag racing is a type of motor racing in which automobiles or motorcycles (usually specially prepared for the purpose) compete, usually two at a time, to be first to cross a set finish line. The race follows a short, straight course from a standing start over a measured distance, most commonly ¼ mile (1,320 ft (402 m)), with a shorter 3/16 mile 10 feet (1,000 ft (305 m)) used by nitromethane powered Top Fuel dragsters and funny cars along with some bracket races, while 660 ft (201 m) (1/8 mi) is also popular in some circles. Electronic timing and speed sensing systems have been used to record race results since the 1960s.
