Native American Heritage Day is a civil holiday observed on the day after Thanksgiving in the United States.

National legislative history
President George W. Bush signed into law legislation introduced by Congressman Joe Baca (D-Calif.), to designate the Friday after Thanksgiving as Native American Heritage Day. The Native American Heritage Day Bill was supported by the National Indian Gaming Association (NIGA) and 184 federally recognized tribes, and designates Friday, November 28, 2008, as a day to pay tribute to Native Americans for their many contributions to the United States.

The Native American Heritage Day Bill encourages Americans of all backgrounds to observe the day after Thanksgiving as Native American Heritage Day, through appropriate ceremonies and activities. It also encourages public elementary and secondary schools to enhance student understanding of Native Americans by providing classroom instructions focusing on their history, achievements, and contributions.
