The Arizona Winter League (AWL) was an independent professional winter baseball league. Arizona Winter League games were all played at Desert Sun Stadium in Yuma, Arizona. The league was founded in 2007. It disbanded in 2013 due to parent league, the Golden Baseball League/North American League, folding, but was restarted in 2016, only to fold again following the 2018 season.

The inaugural season consisted of a 21-game regular season, with the first and second-place teams facing off in a one-game playoff for the championship. All teams are based in the Yuma, Arizona area playing all games at Desert Sun Stadium and utilizing the Ray Kroc Complex which used to house the San Diego Padres and Yakult Swallows spring training operations. The league is a professional winter league that includes a number of ex-major league stars as managers and instructors including Mike Marshall, Garry Templeton, Ozzie Virgil Jr., Les Lancaster, Darrell Evans, and Cory Snyder, most of whom manage independent league teams in the North American, American Association, and Frontier Leagues or are coaches in the minor league system for big league clubs.

In the first five years, over 225 players have left the AWL with professional contracts. Two pitchers from the 2007 Arizona Winter League, Scott Richmond and Sergio Romo have reached the major leagues pitching for the Toronto Blue Jays and San Francisco Giants respectively in 2008.

Announced on November 15, 2006, and headquartered in Yuma, Arizona by the Golden Baseball League, it is an independent baseball league which consists of ten teams based out of the San Diego Padres former spring training complex in Yuma.

The Arizona Winter League debuted January 19, 2007, with four charter teams: the Canada Miners, Yuma Scorpions, Snow Falcons, and Sonora Surf Dawgs, under GBL team management. These respective teams began using the logos, caps and uniforms of past GBL teams such as the San Diego Surf Dawgs (Sonora), Mesa Miners (Canada) and the Surprise Fightin' Falcons (Snow) with the lone exception of the Scorpions, whose identity is the same as their GBL brethren.

The league was a surprising source of players for the GBL and major league organizations in its first season as 37 players were signed by independent pro teams and the Baltimore Orioles, Kansas City Royals, Philadelphia Phillies, and Boston Red Sox also signed players out of the AWL as well.

For the 2008 season, the league added two expansion teams, the Blythe Heat and Palm Springs Chill, the Sonora Surf Dawgs reverted to the previously known San Diego Surf Dawgs and the Snow Falcons were renamed the Sonora Pilots. The Heat and Chill play their home games at respective California ballparks. In addition, the league expanded beyond its affiliation with the Golden Baseball League and had Can-Am League, Frontier League, Northern League, and American Association teams represented in the instructor ranks and eligible to draft players at the end of the AWL. Over 40 players were drafted and signed by independent, foreign professional, and major league organizations.

For the 2009 season, the league expanded once again and added two more teams, the San Luis Atleticos and the Saskatchewan Silver Sox. In addition, the Sonora Pilots did not return in 2009 and were replaced by Team Canada. The 2009 AWL started a new format with two divisions: The International Division had Team Canada, Western Canada, Saskatchewan, and San Luis, while the American Division comprised Palm Springs, San Diego, Blythe (defending champions), and Yuma. The 20-game season finished up on February 27 and then had a single-elimination semi-final between the top two teams from each Division. A championship game the next night, which is the winter highlight event in Yuma each year and heavily attended, pitted the semi-final winners in a winner-take-all game. A record 47 players were drafted and signed out of the 2009 AWL.
