Peninsula is a village in northern Summit County, Ohio, United States, along the Cuyahoga River.

Peninsula is located in the middle of the Cuyahoga Valley National Park.

The dominant Greek Revival architecture reflects popular tastes amongst settlers to the Connecticut Western Reserve from New England.

The Gothic Revival Bronson Memorial Church, originally constructed in 1835 as the Bethel Church, according to William Perrin's History of Summit County (1881) was an attempt to “introduce moral and religious tactics among the vicious and unlawful practices of the canal boatmen.” In 1889, the church was remodeled in the Gothic Revival style.

A notable high style example of the village's Greek Revival architecture is the 1824 Bronson House, built of locally quarried sandstone blocks.

Several canal-era houses are typical of the popular Western Reserve New England building type called the Upright-and-Wing, particularly suitable for the early 19th-century Ohio frontier.

The 1886 Stick-style Boston Township Hall originally functioned as the village high school.

The three-story hip-roofed building contains a pyramidal roof tower with an open belfry.

The racial makeup of the village was 98.4% White, 0.4% African American, 0.4% Asian, and 0.9% from two or more races.
