The Kumeyaay, also known as Tipai-Ipai, formerly Kamia or Diegueño, are Native American people of the extreme southwestern United States and northwest Mexico. They live in the states of California in the US and Baja California in Mexico. In Spanish, the name is commonly spelled Kumiai.

The Kumeyaay consist of two related groups, the Ipai and Tipai. The two coastal groups' traditional homelands were approximately separated by the San Diego River: the northern Ipai (extending from Escondido to Lake Henshaw) and the southern Tipai (including the Laguna Mountains, Ensenada, and Tecate).

Nomenclature and tribal distinctions are not widely agreed upon. The general scholarly consensus (e.g., Langdon 1990) recognizes three separate languages: Ipai, Kumeyaay proper (including the Kamia), and Tipai in northern Baja California. Other authorities (e.g., Luomala 1978 and Pritzker 2000) see only two: Ipai and Tipai.

However, this notion is not supported by speakers of the language (actual Kumeyaay people) who contend that within their territory, all Kumeyaay (Ipai/Tipai) can understand and speak to each other, at least after a brief acclimatization period. All three languages belong to the Delta–California branch of the Yuman language family, to which several other linguistically distinct but related groups also belong, including the Cocopa, Quechan, Paipai, and Kiliwa.
