MarsCon 2023 - When Books Come Alive!

MarsCon is a fan-run science fiction convention for all ages held every March in the Minneapolis/Saint Paul area. At MarsCon you’ll find panel discussions, parties, guest of honor presentations, science and science fiction, our art show, film/anime room, gaming, dealers room, charity auction, and masquerade. But wait, there's more! Our Con-In-a-Con Comedy Music track attracts performers—and listeners—from across the country.

The twenty-fifth edition of MarsCon (I know; we can scarcely believe it) will take place March 10 - 12, 2023 at the Hilton Minneapolis/St. Paul Airport Mall of America. You are invited!

News From MarsCon:

An extremely preliminary program schedule appears! Check it out.

How do we get the ideas to fill the program schedule? From you, once you add your suggestion(s).

The 2023 Charity Auction will benefit Geek Partnership Society and the Gordy Dickson Memorial Scholarship Fund.
