Fort Collins Public Library, Public library in Fort Collins, Colorado.

Fort Collins Public Library is a public library system with multiple locations serving the Fort Collins area. The system provides book collections, digital resources, and materials that support research and learning.

The system grew from a private book collection in the late 1800s that eventually became a public library service. A donor's gift resulted in the construction of the first dedicated library building in 1903.

Since 2016 the district has hosted the annual Fort Collins Book Fest, with themes such as Beer, Science and Food. The district's local history collection on Fort Collins and Larimer County is extensive, and its special archive moved to the Fort Collins Museum of Discovery on 1 April 2007.

The main location is centrally situated with extended hours Monday through Thursday and shorter hours on weekends. It is helpful to check specific opening times before visiting since schedules may vary on holidays.

The collection holds original Sanborn Fire Insurance maps spanning several decades that document the city's physical growth in detail. These maps reveal building structures and street layouts from past periods and offer valuable insight into the city's development.
