Business leagues are associations of people with common business purposes, and they exist to improve and advance member business interests and/or support favorable business conditions. While they sometimes conduct business directly, they are legally prohibited from distributing profits to individual members or staff.

With $81 million in revenue in 2012, the largest business league in Arizona is The Marine Preservation Association which has a national scope.

The Thunderbirds, which hosts the Waste Management Phoenix Open, is the second largest business league with $26 million in revenue. Several Arizona’s chambers of commerce and visitors and convention bureaus are also on the list of top business leagues.
