Louisville began as a mining community in 1877 and has evolved into a sought-after residential area in southeastern Boulder County. Named for local landowner Louis Nawatny, the city boasts a historic downtown centered around Steinbaugh Pavilion, which hosts summer concert series and transforms into an ice skating rink in winter. The Coal Creek Trail and Davidson Mesa Trail are among the 32 miles of recreational paths winding throughout the community, offering residents extensive options for hiking, biking, and walking.

Rental options in Louisville include boutique apartment communities and single-family homes, with average rents around $1,834 per month. The downtown district along Main Street features local boutiques, art galleries, and independent restaurants housed in preserved historic buildings. The Louisville Farmers Market, held at Steinbaugh Pavilion on Saturdays from May through October, brings fresh produce and artisanal goods to the community. Notable employers in the area include Sierra Space and Uber's Louisville office, making the city attractive for professionals in technology and aerospace sectors. The city's median household income of $133,388 reflects the affluent nature of the community.

Located just 10 miles east of Boulder and about 25 miles northwest of Denver, Louisville provides convenient access to both cities via U.S. Highway 36. RTD bus routes and the nearby US 36 Bikeway connect residents to the greater Denver metropolitan area, while the Rocky Mountains offer year-round outdoor recreation opportunities. The city experienced significant rebuilding following the 2021 Marshall Fire, which has resulted in newer construction in some neighborhoods. Louisville's combination of historic downtown character, outdoor recreation access, and proximity to major employment centers makes it one of Colorado's most appealing communities.
