L'acido dimetilarsinico (DMA o DMAA), chiamato anche acido cacodilico o dimetilarsinato, è un composto chimico dell'arsenico.

Come gli altri composti metilati dell'arsenico risulta meno tossico dell'arsenico inorganico in quanto entra nei meccanismi di detossificazione di alcuni organismi[3]; tuttavia risulta potenzialmente cancerogeno[4].

È anche noto come Agente Blu, perché durante la Guerra del Vietnam gli USA lo utilizzavano per la deforestazione e i contenitori di questo acido erano identificati con delle bande blu dipinte sopra.
