Hill's Academy is a historic school building at 22 Prospect Street in Essex, Connecticut.

The town then established the Essex Historical Society to receive the property and to preserve local history.

The front facade is three bays wide, articulated by brick pilasters painted white, which rise to an entablature and fully pedimented gable.

Each floor has a single large chamber, which functioned as classrooms during the building's academy phase.

[2] The academy was founded in 1831 through the efforts of John Hill, a local businessman, and this building was completed the following year.
