America First Field (formerly Rio Tinto Stadium and referred to as The RioT) is a soccer-specific stadium in Sandy, Utah, United States. It is the home of Real Salt Lake of Major League Soccer (MLS) and the Utah Royals of the National Women's Soccer League (NWSL). The stadium opened on October 9, 2008, and seats 20,213 for soccer, but can be expanded to over 25,000 for concerts. It has also been expanded to 22,213 via temporary seating for soccer games when increased demand calls for it.

The stadium hosted the 2009 MLS All-Star Game, the second leg of the 2011 CONCACAF Champions League Finals, and the final of the 2013 Lamar Hunt US Open Cup. It was also a host stadium during the 2013 CONCACAF Gold Cup, and a host for final stages of the 2015 CONCACAF Men's Olympic Qualifying Championship.

Rio Tinto's naming rights were to expire in December 2020 but the stadium retained its branding through 2021. Real Salt Lake sought a ten-year commitment from its next stadium naming rights partner. In September 2022, RSL announced a naming rights agreement with America First Credit Union with the stadium renamed America First Field.
