The Chan-Ya-Ta Site (13BV1) is a Late Prehistoric village in Buena Vista County, Iowa, United States, in which Native Americans lived in large earthlodge structures surrounded by a fortified ditch.

The site is part of the Mill Creek Culture, which flourished in northwest Iowa 1100-1200 CE.

[2][3] The site name is an amalgam of the first letters of the names of the different landowners who allowed access to the site, and is pronounced "chen-yata".

It was the scene of the first Iowa Archeological Society field school.
