早熟禾（学名：Poa annua）为禾本科早熟禾属下的一个种。

Poa annua, or annual meadow grass (known in America more commonly as annual bluegrass or simply poa), is a widespread low-growing turfgrass in temperate climates. Though P. annua is commonly considered a solely annual plant due to its name, perennial bio-types do exist. 'Poa' is Greek for fodder. It is one of the sweetest grasses for green fodder, but less useful than hay. This grass may have originated as a hybrid between Poa supina and Poa infirma.
