后推（英语：Pushback）是指将飞机推离登机桥或泊位的作业。

由于在登机桥位，飞机并没有足够的空间掉头，而在这些地方使用反向推力，一般都是不被允许的（以避免发动机的喷射流损坏附近的建筑物与设备），后推作业于是成为必要。在繁忙的机场，后推作业需要得到航空交通管制员的批准，以协调滑行道的交通。因此，如何有效管制后推作业亦是航空交通管制员的重要课题。

In aviation, pushback is an airport procedure during which an aircraft is pushed backwards away from an airport gate by external power. Pushbacks are carried out by special, low-profile vehicles called pushback tractors or tugs.

Although many aircraft are capable of moving themselves backwards on the ground using reverse thrust (a procedure referred to as a powerback), the resulting jet blast or prop wash may cause damage to the terminal building or equipment. Engines close to the ground may also blow sand and debris forward and then suck it into the engine, causing damage to the engine. A pushback is therefore the preferred method to move the aircraft away from the gate.
