Professor Elvin Gadd's Lab is the lab where Professor Elvin Gadd lives. The lab used to be tiny and on Thwomp Mountain (as seen in Mario & Luigi: Partners in Time) however after the volcano exploded and destroyed his lab, he moved to a newer and better one in Boo Woods.

The lab's first appearance was in Luigi's Mansion. It had a Gallery where E. Gadd had pictures of ghosts but the ghosts all escaped into Luigi's Mansion.

E. Gadd also has a garage as a game board as seen in Mario Party 6.
