The Acjachemen (/ɑːˈxɑːəməm/) are an Indigenous people of California. Published maps often identify their ancestral lands as extending from the beach to the mountains, south from what is now known as Aliso Creek in Orange County to Las Pulgas Canyon in the northwestern part of San Diego County. However, sources also show that Acjachemen people shared sites with other Indigenous nations as far north as Puvunga in contemporary Long Beach.

The Acjachemen language does not have any fluent speakers. It is closely related to the Luiseño language still spoken by the neighboring Payómkawichum (Luiseño) people.
