The 27-year-old enjoyed the best seasons of his career at Rio Tinto between 2007 and 2010.
Real Salt Lake announced the club has reacquired the American striker, who was cut loose from his contract with Championship side Nottingham Forest this week. RSL sent allocation money to the Portland Timbers, who owned Findley's rights after selecting him in the 2010 expansion draft.
The 27-year-old striker played for RSL from mid-2007 through 2010, where he scored 29 goals and added 13 assists in 96 regular season matches. He was a member of the 2009 MLS Cup-winning squad.
“RSL has played a huge role in my career and I’m very excited to be back in Utah,” Findley said. “RSL is a team that is consistently at the top of the table and always has plenty of talent. Jason Kreis and the coaching staff are very dedicated and know what it takes to be successful."
With Forest, Findley scored six goals in 29 games overall, making just 10 league starts in an injury-plagued stay. Internationally, he has 11 caps for the USA, including three appearances at the 2010 World Cup in South Africa.
