The Delmarva Peninsula gets its name from the three states it’s a part of: DELaware, MARyland, and VirginiA. You could say Delmarva is technically an island, since you have to cross one of five bridges (one of them being the 20-mile long Chesapeake Bay Bridge-Tunnel) to get across the Chesapeake and Delaware Canal, but since the canal is man-made it’s still considered a peninsula.
