Lory State Park, Natural recreation area in Larimer County, US.

Lory State Park is a state park in the Rocky Mountain foothills spanning around 2,500 acres. It features trail networks through montane forests and grasslands, along with facilities for biking, hiking, and other outdoor activities.

Lory State Park is named for Charles A. Lory, president of Colorado Agricultural College (now Colorado State University) from 1909 to 1940. The land west of Fort Collins was assembled into a state park and later bordered Horsetooth Reservoir, created by the Horsetooth Dam on the Cache la Poudre River. The park lies in Larimer County at about 1,963 metres above sea level.

The park is named for Charles A. Lory, president of Colorado Agricultural College (now Colorado State University) from 1909 to 1940; the college's forestry camp once occupied this land west of Fort Collins. The sign at the entrance reads "Welcome to your Charles A. Lory State Park" beneath a Colorado Parks & Wildlife band.

The park opens daily from early morning until sunset and provides parking areas at the main entrances. Visitors should prepare for elevation changes on trails and bring plenty of water for longer hikes.

The park has its own bike park with dirt jumps, a pump track and a skills area, alongside the trails used for mountain biking, hiking, horseback riding and rock climbing. It sits west of Fort Collins, west of Horsetooth Reservoir and north of Horsetooth Mountain Park, at about 1,963 metres.
