Kalapuya

The Kalapuya or Kʼalapʰuya are a Native American people, which had eight independent groups speaking three mutually intelligible dialects. The Kalapuya tribes' traditional homelands were the Willamette Valley of present-day western Oregon in the United States, an area bounded by the Cascade Range to the east, the Oregon Coast Range at the west, the Columbia River at the north, to the Calapooya Mountains of the Umpqua River at the south.

Today, most Kalapuya people are enrolled in the federally recognized Confederated Tribes of the Grand Ronde Community of Oregon; in addition, some are members of the Confederated Tribes of the Siletz. In both cases descendants have often intermarried with people of other tribes in the confederated tribes, and are counted in overall tribal numbers, rather than separately. Most of the Kalapuya descendants live at the Grand Ronde reservation, located in Yamhill and Polk counties.
