Port Hudson State Historic Site
The Port Hudson State Historic Site is located on the Mississippi River north of Baton Rouge in East Feliciana Parish, Louisiana, just outside the limits of Port Hudson and in the vicinity of Jackson.

It was designated a National Historic Landmark in 1974, significant as the first place where African-American military units fought for the Union Army under African-American field leadership.
