The Chimakum, also spelled Chemakum and Chimacum, Native American people (known to themselves as Aqokúlo and sometimes called the Port Townsend Indians[1]), were a group of Native Americans who lived in the northeastern portion of the Olympic Peninsula in Washington state, between Hood Canal and Discovery Bay until their virtual extinction in 1902.

It was spoken until the 1940s on the east side of the Olympic Peninsula between Port Townsend and Hood Canal.

[4] Franz Boas, considered one of the main authorities on local Indian linguistics, cites a tribal member named Louise as his source for over 1200 original Chimakum words and dialects.

Louise, a dual speaker of both Clallam and Chimakum, was able to verbally recite words for Boas to document into his extensive logging of local Native American Languages in the Pacific Northwest Region.

[3] Around 1789, there were about 400 Chimacum Indians living on the Quimper Peninsula and along Hood Canal, about 2000 Clallams spread in 16 villages from Discovery to Clallam Bay, another 2000 Makahs and Ozettes at Neah Bay and west of Lake Ozette, and another 500 Quileutes to the south, making the number of native peoples roughly about 6000.

[8] Shortly before 1790 they were fighting a number of tribes, including the Snohomish, Snoqualmie, Klallam, Makah, and Ditidaht (or Nitinaht).

The father was recognized as the man responsible for the death of respected Suquamish Tulébot, which had been one of the pretexts for war.

According to Edward S. Curtis, recounting Wahélchu's telling, "the rapid rain of bullets mowed them down."

[2] The few surviving Chimakum, including the primary chief who had gone upstream early that morning, subsequently joined the Twana, or Skokomish, at the head of Hood Canal.

In 1936–37 the federal government established Klallam reservations for the Lower Elwha and Port Gamble communities.

In 1957 the commission recognized the Klallam claim of possession of the Chimakum lands at the time of the treaty and granted compensation of over $400,000.

[3] In 1962, skeletal remains of slain Indians were discovered by a dozer doing some work around the Chimacum Creek area, and after proper excavation by Lewis Agnew, a retired archaeologist recently relocated to Port Townsend, two Indian skeletal remains were unearthed with stone arrows still lodged in their bones from sometime prior to the road being constructed through that area in 1860.
