Due to ongoing construction in and around Moser Hall, the museum will be closed to the public until August 29th, 2022.


The product of a generous donation from a local family, The Clarence R. Smith Mineral Museum showcases high quality specimens from around the world! Conveniently located on the campus of Youngstown State University, the museum lies within walking distance of several local points of interest. Stop in for a minute or an hour, by yourself or with a group, during open hours or by appointment; the Clarence R. Smith Mineral Museum is here for the education and enjoyment of the community!

Wondering when you can stop in for a visit?

Regular open hours on Mondays through Fridays from 9AM-3PM will resume August 29th, 2022. The museum will again offer open hours on select Saturdays this fall semester. Check back soon for a list of dates!
