Fall River (Wyoming, Idaho): Fall River rises on the Madison and Pitchstone plateaus in the southwest corner of Yellowstone National Park, Wyoming and flows approximately 64 mi to its confluence with the Henrys Fork of the Snake River near Ashton, Idaho.  Historically, the river was referred to as the Middle Fork of the Snake River or as Fall River or the Falls River by trappers and prospectors as early as the 1830s.  It was officially named the Falls River by the 1872 Hayden Geological Survey, but was always called Fall River by the locals and so the U.S. Board on Geographic Names changed the official name to Fall River in 1997 at the request of Idaho authorities.  The river is home to numerous waterfalls and cascades in its upper reaches.

Fall River (MBTA station): Fall River is a future railroad station on the MBTA Commuter Rail's South Coast Rail project, located in Fall River, Massachusetts.

Quequechan River: The Quequechan River is a river in Fall River, Massachusetts, that flows in a northwesterly direction from the northwest corner of the South Watuppa Pond through the heart of the city of Fall River and into to the end of the Taunton River at Mount Hope Bay at Heritage State Park/Battleship Cove.  The word Quequechan means "Falling River" or "Leaping/Falling Waters" in Wampanoag, hence the city's name.

She was the seventh ship of the United States Navy to be named in honor of the sixth state, and one of two ships of her class (along with her sister "Alabama" ) to be donated for use as a museum ship.

Blackstone River and Canal Heritage State Park: The Blackstone River and Canal Heritage State Park is a part of the state park system of the Commonwealth of Massachusetts, managed by the Massachusetts Department of Conservation and Recreation (DCR).  This 1000 acre park "recalls the role of canals in transporting raw materials and manufactured goods between emerging industrial centers."  The Blackstone River and Canal Heritage State Park at Uxbridge, Massachusetts, is the midpoint of the Blackstone River Valley National Heritage Corridor of the National Park System.  The Blackstone River and Valley is where the industrial revolution was born in America.

Located near the Flint Hills, Fall River State Park is 980 acre and can be accessed by going along 144 Highway 105.

Fall River Pass: Fall River Pass (elevation 11,796 ft ) is a mountain pass in the Rocky Mountains of northern Colorado in the United States.  It is located in the Front Range, within Rocky Mountain National Park.  The pass is traversed by U.S. Highway 34 on Trail Ridge Road between Granby and Estes Park.  However, as at Milner Pass on the Continental Divide, the road does not descend after reaching the pass from the west, but instead continues to climb along a side ridge; thus, neither pass is the high point on Trail Ridge Road, which crests at 12,183 ft east of Fall River Pass, still within Rocky Mountain National Park.  On the other hand, the old, largely unpaved, and one-way-uphill Fall River Road (see adjoining map) does have its summit at Fall River Pass, where it joins the modern highway for the descent to the west.

Battleship Cove: Battleship Cove is a nonprofit maritime museum and war memorial in Fall River, Massachusetts.
