Wolfenstein 3D Add-On is a map set for registered Wolfenstein, made by Bryan Baker. It appeared as set P in the Wolfmaster map pack in 1994. Baker was one of several people who worked on MapEdit.

The maps are primarily large in size, and of admirable quality for their age. All levels are featured on Episode 1.

The levels had formerly appeared in Wolfen60's Episode 5 and December 1992's Wolf1A, with only level 6 being unique to Wolfenstein 3D Add-On.
