Dat So La Lee House, Historic residence in Carson City, United States.

The Dat So La Lee House is a modest one-story board and batten cottage at 331 W. Proctor St. in Carson City, Nevada. It faces north onto West Proctor Street and is set back about 40 feet behind a small lawn and parking area. It was built by Abram Cohn, husband of Louisa Keyser's promoter Clarrise Amy Cohn.

Built in the early 1900s, the house gained recognition when it was added to the National Register of Historic Places in 1994. The designation reflected its importance to the story of Washoe people and Nevada's frontier era.

The house is also called the Louisa Keyser House, after the name Dat So La Lee used in dealings with her promoter Amy Cohn. Dat So La Lee, a Washoe basket weaver, lived here; the cottage was built by Cohn's husband Abram. It remains a private residence, not a museum, so its story is read from the street and from records rather than from exhibits.

The house is also called the Louisa Keyser House, after the English name Dat So La Lee used. It was built by Abram Cohn, husband of Clarrise Amy Cohn, who promoted her basketry. The cottage sits about 40 feet back from West Proctor Street behind a small lawn and parking area.
