Tucson Singletarians is a social group for single adults aged 50+ in Tucson.

The Tucson Singletarians is a community group for single adults aged 50 and older in Tucson, offering a welcoming environment for socializing and friendship. Membership requires an annual application, agreement with the group's philosophy, participation in at least one activity, and the payment of $35 in annual dues. First-time members aged 85 and above may pay a one-time fee of $35, or $30 if they sign up at a Meet and Greet, while current members aged 85 or older are exempt from annual dues. The group welcomes those who are never married, widowed, divorced, or separated, and allows current members in good standing to marry; however, if a partner does not join, the original member must leave. New partners may attend three functions before becoming members. The organization encourages prospective members to attend several social events before deciding to join, noting that some gatherings may have lower attendance and that working on club projects can serve as an ice-breaker. The group aims to help new members feel comfortable and welcome, acknowledging that initial events may not immediately reveal established friendships but hoping for shared connections over time.
