Trunk-or-Treat is a service event geared toward UMSL families and the surrounding community. Started in 2010, this program has grown from 75 children to nearly 400 attending! It takes place on the Saturday before Halloween (if Halloween falls on a Saturday, it takes place on that day). This year's event is on October 31, 2020 from 12 p.m.-2 p.m. in the MSC Garage South (on North Campus). 

It is intended to:

1) provide a safe and fun way for families to enjoy Halloween festivities

2) early exposure of a collegiate environment to children

3) increase the community’s knowledge about the campus. The attendants will enjoy various activity booths, coupled with “trunk-or-treating,” which means they go from trunk to trunk getting treats! Costumes are encouraged but not required. This event is for children ages 0-12. 

Trunk Example

UMSL student organizations, departments/offices, and individuals can provide trunks (including treats), or create an activity booth. Departments and offices are also welcome to share materials they may serve the needs of community members. Prizes for the best trunk and costume (student, staff, or faculty member) are on the line. 

UMSL student organizations, offices, and departments can register to participate from September 16 until 11:45 p.m. on October 18 at
