Marysville is a small unincorporated community in Lewis and Clark County, Montana, United States. In the 1880s and 90's it was a bustling mining town of three thousand residents, and was the center of gold mining in Montana. A few buildings remain, including a baseball field with bleachers. The population now consists of a few local residents, most of whom commute to and work in nearby Helena. Just up the dirt road is Great Divide Ski Area, while down the road is the Silver City Saloon on Highway 279.
