The Amanda Blake Store is a historic building located at 104 Main Street in the city of Port Republic in Atlantic County, New Jersey. Built in 1884 as a general store, it was added to the National Register of Historic Places on January 25, 1979, for its significance in commerce and social history. It is now a privately-owned house. The building was listed as a contributing property of the Port Republic Historic District in 1991.

The two-story frame Victorian store was built in 1884 for William Blake, a farmer from Chestnut Neck, and his daughter Amanda Blake, after whom the store is named. She became a milliner and operated the store. She was also the postmistress, from 1918 to 1940, for the post office located in the store. In the evenings, the store was used as a social gathering place, and a meeting place for the Independent Order of Mechanics.
