Bullfrog Basin is one of the National Park Service recreation sites of the Glen Canyon National Recreation Area of Kane County, Utah, United States, adjoining Lake Powell. It encompasses Bullfrog Basin Airport (IATA: BFG, ICAO: U07, FAA LID: U07), the Bullfrog Resort and Marina, the Bullfrog terminus of the Charles Hall Ferry, and a campground.

It is nearby the 1970s mining town Ticaboo. The National Park Lodge in the site is named Defiance House Lodge. Built on a bluff that overlooks the Bullfrog Bay part of Lake Powell, it is a stucco building with several adjoining prefabricated units. Bullfrog Basin has a USNPS visitor centre, and the Bullfrog Resort and Marina includes a restaurant, shops, and a gas station.

Its development was personally championed by Calvin Rampton in the 1960s, who secured a US$2.7 million funds-matching grant from the Economic Development Administration in 1966 to pave an access road to the area. Although the road did not connect to a settlement at either end, the USNPS had already spent US$1.5 million on clearing the area for the aforementioned airport, marina, and campground; along with a planned restaurant, boat ramp, motel, and visitor centre.

The Lake Powell Parkway, originally planned as part of the USNPS Mission 66 (a.k.a. the Grand Circle) road system, would have joined Bullfrog to US-89 near Page, Arizona in one direction and to I-70 near Moab, Utah in the other, and would have significantly increased access to Bullfrog.
