蝴蝶式车门（Butterfly doors）即原属于超级跑车和原型赛车车门的一种样式。将车门开启后，呈现出「蝴蝶展开翅膀的样貌」而得名。

固定车门的活动机件置身于车体A柱部位，从下方往上方开启车门后，使乘坐人员得以顺利进出。

Butterfly doors or vertical doors are a type of door sometimes seen on high-performance cars. They are similar to scissor doors. While scissor doors move straight up via hinge points at the bottom of the A-pillar, butterfly doors move up and out via hinges along the A-pillar. This makes for easier entry/exit at the expense of requiring more opening space than needed for scissor doors.
