Lobster Wars, also known as Deadliest Catch: Lobstermen in the United Kingdom, is a documentary television series on the Discovery Channel. It documents men and one woman fishing for lobsters off the Georges Bank near the northeastern coast of North America. It first aired on August 23, 2007.

Like the similarly themed Deadliest Catch, Lobster Wars is produced by Original Productions for Discovery, and is based on a pilot miniseries also produced by Original Productions, Lobstermen: Jeopardy at Sea. Executive Producer Thom Beers narrates the show in the US whereas voice artist Bill Petrie narrates it in the UK. The show features six boats: The Dragon Lady, The Timothy Michael, The William Bowe, The Direction, The Rachel Leah and The Excalibur — a fishing trawler that causes high tensions between the other 5 boats.
