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.

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: You can schedule your own activity or get-together in next month’s calendar by submitting a Calendar entry to our Calendar Editor at:

Note: To protect the privacy of our hosts, home addresses, personal email addresses, and phone numbers 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.
