The Tryon Creek State Natural Area is a state park located primarily in Portland, in the U.S. state of Oregon. It is the only Oregon state park within a major metropolitan area. The 645-acre (261 ha) park lies between Boones Ferry Road and Terwilliger Boulevard in southwest Portland in Multnomah County and northern Lake Oswego in Clackamas County and is bisected from north to south by Tryon Creek.

The park includes hiking trails, a paved bicycle path, and horse trails. The 3-mile (4.8 km) bicycle path, which runs along Terwilliger Boulevard on the east edge of the park to Lake Oswego, is part of the Portland metropolitan area's system of greenway trails known as the 40 Mile Loop. Near the main entrance off Terwilliger, part of the parking lot is devoted to horse trailers. Riders can choose between the 2-mile (3.2 km) North Horse Loop and the 3-mile (4.8 km) West Horse Loop. Hikers can use the bike path, the horse trails, and 8 miles (13 km) of hiking trails. The paved 0.35-mile (0.56 km) Trillium Trail, a loop furnished with drinking fountains and interpretive signs, can accommodate wheelchairs.

A park building called the Nature Center is near the main park entrance. It has a small play area for toddlers, a gift shop, a large classroom, and a separate area for educational exhibits. Nearby is the Glenn Jackson Shelter, a covered structure for outdoor events.

In 1850, Socrates Hotchkiss Tryon, Sr., pioneer settler, established a donation land claim at the south end of the canyon. Five years later, he died, leaving the land to his wife, Frances. The land then passed to other relatives, including Socrates Tryon, Jr., who sold the 645 acres (261 ha) in 1874 to the Oregon Iron Company. For nearly 25 years, the company logged virgin cedar and fir to use in its foundry in Lake Oswego. Its logging road later became Old Iron Mountain Trail in the state park. In 1900, fire in the upper canyon left charred snags still visible along the park's Center and Big Fir trails.
