St. Aloysius Roman Catholic Church is a historic church at 202 Mt. Mercy Drive in Peewee Valley, Kentucky. It was built in 1914 and added to the National Register in 1989.
It is a small Late Gothic Revival-style church. To its northeast is a historic rectory which has been so altered that it was deemed non-contributing, and a non-contributing 1950s school building associated with the church.
It is built of limestone. It has corner towers and a "boldly crenelated front vestibule".
