Native American Heritage Day is a civil holiday observed on the day after Thanksgiving in the United States. President George W. Bush signed into law legislation introduced by Congressman Joe Baca (D-Rialto), 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.
