St. Paul's Reformed Church is a historic former Evangelical and Reformed Church congregation near the village of Navarre in Stark County, Ohio, United States.

Established in the 1830s, it remained in existence into the 1990s, and while it has since withered away into nonexistence, its early twentieth-century church building survives and has been named a historic site.

[4] In the early twentieth century, St. Paul's was the social center for the small unincorporated community of Smoketown, and the church membership roll comprised hundreds of names, but both community and church have dwindled; every Smoketown business has closed, and while the congregation remained active into the 1990s, it is no longer active.

By the late 2000s, only one previous member remained active, spending church money and his own funds to keep the building in repair, although the building was no longer in use aside from occasional weddings.

It is one of four Register-listed locations in the vicinity of Navarre, along with the Loew-Define Grocery Store and Home, the Rochester Square Historic District, and the Stahl-Hoagland House.
