The Alsea are a Native American tribe of Western Oregon. They are (since 1856), confederated with other Tribes on the Siletz Reservation, Oregon, and are members of the Confederated Tribes of Siletz. Their origin story says that the Yaquina, Alsea, Yachats, Lower Umpqua, and Siuslaw people are all one tribe, and speak the same language. Today however, the Yakonan language branch is divided into Alsean and Siuslawan. The Alsean people (Yaquina/Alsea/Yachats) all practiced forehead flattening (by slight pressure applied in baby’s cradleboard) until about 1860. The Alsea signed the 1855 Coast Treaty, agreeing to share their homelands with other Tribes when the Siletz Reservation was to be established, the treaty not being ratified by the U.S. Senate, the appropriations never arrived.

The lawsuit “Alsea Band of Tillamooks et al vs the United States”. The confederated Tribes of Siletz Indians won that case, and some compensation was received about 1959.
