总温（亦称停滞温度、滞温、全温）（对应英文的Total Temperature、Stagnation Temperature），是一个与空气动力学相关的名词。

流体在流动时具有它的压力、温度、密度、速度、马赫数。如能使一流体以绝热过程完全静止时，那么它的动能将转化为内能，反映在压力、温度与密度上。此时之温度便为总温。实际例子为航空器的皮托管在前端量测的便是总温与总压。

流体总温与静温的关系式为与马赫数有关的函数：

其中：

In aviation, stagnation temperature is known as total air temperature and is measured by a temperature probe mounted on the surface of the aircraft. The probe is designed to bring the air to rest relative to the aircraft. As the air is brought to rest, kinetic energy is converted to internal energy. The air is compressed and experiences an adiabatic increase in temperature. Therefore total air temperature is higher than the static (or ambient) air temperature.
