We have a full schedule of social activities each month, ranging from lunches and happy hours to games nights, discussion groups, trivia, and our Speakers Forum.

All events are open to all Mensa members, and to guests who accompany Mensa members. Events in public places (restaurants, theaters, etc.) are also open to prospective members. RSVPs are not required, except as noted.

To protect the privacy of our hosts, home addresses and personal email addresses are not listed on this website. Current members of Orange County Mensa can access this information in the current Oracle newsletter or the weekly eBlast.

The calendar of activities in the Oracle (our monthly newsletter) may include additional events that are open only to Mensa members and their guests. To view the Calendar in the Oracle, please visit American Mensa’s local group newsletters webpage. Have your Mensa log-in info (email address and password) ready.

Once a week, we send an Email Blast — “This Week in OC Mensa” — that lists the activities for the next seven days to each member with an email address on file with American Mensa.

Mensa members only, please: Sign up for the Weekly eBlast, “This Week in OC Mensa.” Use your preferred email address. Receive the OCM activities for the next seven days delivered to your email inbox.

Canceled          OC Mensa’s 40th Anniversary Celebration

Due to the National Emergency to curb the spread of the COVID-19 virus and the cautions about large group events, we decided to cancel Orange County Mensa’s 40th Anniversary Celebration scheduled for Sunday, April 5th.  Those who sent in reservations are being issued refunds. We may reschedule for a later date, but everything depends on how the situation evolves.
