The Chaluka Site is a historic area near Nikolski, Alaska. It was discovered in the early 20th century but was only initially excavated in 1938.

The Chaluka Site is archaeologically significant for the role it played around 4000 BC to 1500 AD. With the artefacts excavated in the area, experts believe that it is the site where the ancient Aleuts lived. Evidences also show that the area was used by cultures that were based on maritime economies. They have managed to recover hunting and manufacturing tool as well as ornaments.

Visitors can find an oval mound measuring 6 meters height by the mouth of the Unmak Creek. It was listed on the National Register of Historic Places in 1966, years after it was declared as a National Historic Landmark.
