战神五号运载火箭(原称为货物运载火箭或称CaLV),是星座计划中的货物运载火箭，战神五号运载火箭将在NASA计划的重返月球运载牵牛星号登月舱和地球出发级。重返月球计划由战神一号运载火箭运载猎户座太空船与战神五号运载其它舱组结合在一起飞向月球。战神五号运载火箭的酬载能力是287,000磅(130.18公吨)到低地球轨道,或者143,300磅(65公吨)到月球轨道。战神系列运载火箭的战神是由希腊神话命名而来。 2010年10月美国总统签署法案，包括战神五号火箭在内的星座计划宣告终结，但相关技术很可能用于未来的太空探索计划。

The Ares V (formerly known as the Cargo Launch Vehicle or CaLV) was the planned cargo launch component of the NASA Constellation program, which was to have replaced the Space Shuttle after its retirement in 2011. Ares V was also planned to carry supplies for a human presence on Mars. Ares V and the smaller Ares I were named after Ares, the Greek god of war.
