Fishing Bridge RV Park, Recreational vehicle park in Yellowstone National Park, United States.

Fishing Bridge RV Park is a paved campground of 310 hard-sided sites with full hookups for water, sewer and electricity, laid out in loops off the Grand Loop Road where the Yellowstone River leaves Yellowstone Lake. It sits at about 7,800 feet (2,377 m) in Park County, Wyoming, and is the only campground in Yellowstone National Park with complete utility connections.

Fishing Bridge RV Park occupies the site of a campground built by the National Park Service near the outlet of Yellowstone Lake, where the Fishing Bridge area had long drawn anglers. The present park was rebuilt and reopened in 2018 after a multi-year reconstruction that replaced its aging utility system and reorganized the sites. It remains the only campground in Yellowstone with full hookups.

Fishing Bridge takes its name from a 1902 bridge at the outlet of Yellowstone Lake where anglers once lined the railings. Today the park is a base for watching cutthroat trout spawn in the Yellowstone River in late spring and for evening ranger programs at the nearby visitor center.

Fishing Bridge RV Park accepts only hard-sided units; tents and pop-ups are barred because grizzly bears move through the area. Each site has full hookups for water, sewer and electricity, and the park lies at about 7,800 feet, so rigs should be winterized and engines tuned for the altitude. Check in before dark, since bison and bears often cross the roads at dusk.

The park sits where Yellowstone River exits Yellowstone Lake, giving visitors direct access to North America's largest high-elevation freshwater lake. This location creates unusual opportunities to observe wildlife right from the campground.
