Contoocook River Amusement Park was a trolley park in Penacook, New Hampshire.
The park was developed along the south bank of the Contoocook River.
For twenty cents in 1893, and up until 1925, one could ride 7 miles (11 km) on the trolley from downtown Concord to Penacook to enjoy free entertainment, fireworks, swimming, dancing at a large pavilion, boating, roller-skating, bowling, and even a steamboat ride up the Contoocook River.
Electric Avenue, a dirt road that is part of the Concord Trail System, now leads through a wooded area where trolley car tracks once ran.
Little trace of the park remains.
