Acacesia is a genus of orb weaver spiders with a mostly neotropical distribution. There are six described species in this genus. Species range from South America to Mexico. One species, A. hamata, is found in the US as well.

The backs of spiders in this genus are marked with a dagger shape, outlined in black and surrounded by a triangular folium. On each side of the dagger there are parallel rows of orange-brown dots. Body length of females ranges from 4.3 to 8 mm, of males from 3.6 to 6.5 mm.

As the other species are only known from museum specimens, only the natural history A. hamata is known in any detail.

Ocrepeira and Cyclosa are close relatives of this genus.
