Blackhawk is a rural community near Shaw in Corcordia Parish, Louisiana, United States, on the west bank of the Mississippi River.

In recent years, the Vicksburg District of the U.S. Army Corps of Engineers has worked on strengthening a section of the mainline Mississippi River levee system near Blackhawk.
