The St. Johns River Light is a decommissioned lighthouse in Jacksonville, Florida, U.S., which stands near the mouth of the St. Johns River. It is located on the grounds of Naval Station Mayport in the Mayport area. Constructed in 1858, it was decommissioned in 1929 and replaced with a lightship. It is sometimes known as the "Old St. Johns River Light" to distinguish it from the modern St. Johns Light, built in 1954.

The Old St. Johns River Light was the third lighthouse to be erected at the mouth of the St. Johns. It is the oldest one still standing, and is in fact the oldest surviving building in Mayport. It was added to the National Register of Historic Places in 1976 and underwent restoration in 1980.
