This amazing, diverse, all-vegan community event is held right here in the nation’s 4th largest city. It’s no wonder, since Houston is ranked the 4th “Most Veg-friendly City” in the nation as of 2012, making us the top Texas Veg-friendly city! This festival is produced entirely by volunteers from our nonprofit organization. Our popular event features vegan vendors and exhibitors, family-friendly kids activities, giveaways and more. VegFest Houston promotes an ethical, compassionate and truly sustainable world for all. Ours is one of the most diverse vegan festivals in the nation!!!

VegFest Houston was on hiatus from 2015-2016 while our nonprofit organization launched exciting new outreach projects, created additional annual events, and expanded our fundraising. A larger venue was also sought out in order to meet the needs of our growing festival, as well as a fresh new format. We are pleased to announce the exciting and spacious venue for our VegFest Houston in 2017! Join us at the luxurious Stafford Centre Convention Hall on Saturday, June 17, 2017!

InOMN is sponsored by NASA’s Lunar Reconnaissance Orbiter, NASA’s Solar System Exploration Research Virtual Institute (SSERVI), and the Lunar and Planetary Institute.

Local events have been planned in the past at Rice University, Bellaire High School, HMNS’s George Observatory at Brazos Bend State Park, and the Lunar and Planetary Institute. Check for additional information about these events and more that might have been added.
