Welcome to the Mariposa County Chamber of Commerce!

Mariposa is located at the junction of Highways 140 & 49.  We are the closest gateway to Yosemite Valley, in fact Highway 140 is referred to as the “all weather highway”.  Mariposa retains the historic charm of our Goldrush roots, however, we offer most all modern amenities. 
Mariposa was once the largest county in 
the state, thus our tag line; "The Mother of all Counties".


Be a part of it...

There are more reasons than ever to join the Mariposa County Chamber of Commerce.  We offer more to our members and community than ever before.
