Poudre River Public Library District, Public library network in Larimer County, Colorado.

The Poudre River Public Library District is a public library network in northern Larimer County, Colorado, with branches in Old Town, Harmony Road, and Front Range Village. It holds about 270,000 items and serves more than 177,000 people across Fort Collins and Timnath.

The library started in the late 1800s as a small collection on South College Avenue in Fort Collins. In 1903, a grant from Andrew Carnegie funded its first dedicated building, allowing the collection and its services to grow over the following decades.

The library hosts the Fort Collins Book Fest every year, where readers can meet authors in person and take part in conversations about books and regional themes. The event draws people from across the area and turns the library into a gathering point for the local reading community.

The network has several locations across northern Larimer County, so there is usually a branch within a short distance for most residents. Staff at each location can help first-time visitors find their way and make use of what is available.

The Harmony Library opened in 1998 on Harmony Road as a joint-use facility run by Front Range Community College and the library district. It was the district's second branch, following the Old Town Library built in 1974. The shared arrangement lets students and residents use one building instead of separate college and public libraries.
