The Catalaina Mountains Chapter is one of ten MOAA chapters in the state of Arizona. The Catalina Mountains Chapter began as a satellite chapter of the Tucson Chapter in 2015 and became a stand-alone MOAA chapter in 2022. The Chapter was formed because there were several members of the Tucson Chapter that lived in Saddlebrook, Saddlebrooke Ranch, Oro Valley and Marana, all located north of Tucson. These members, living north of Tucson, wanted to meet somewhere north of Tucson for lunch on a monthly basis.
