Hamburg Sea Devils (NFL Europe)

The Hamburg Sea Devils were an American football team that played in NFL Europe from 2005 to 2007. They played their home games at Hamburg's Volksparkstadion (also home to the German association football team Hamburger SV).

The franchise played its first game on 2 April 2005, losing 24–23 to the Cologne Centurions. The Sea Devils' first win came in Week 3 of the 2005 season, with a 31–24 home victory over the then-struggling Rhein Fire.

Their initial head coach was Jack Bicknell, previously head coach of the defunct Barcelona Dragons and Scottish Claymores. The Sea Devils had directly replaced the Claymores after the 2004 season.

On 1 April 2006, the Sea Devils recorded their first tie in franchise history. At home, they scored 17 points in the second quarter, against the Berlin Thunder. They had blown their 17-point lead before regulation ended. When no one scored in overtime, the game ended in a draw. This was only the second tie in the NFL Europa history. The previous tie came in the 1992 season between the Rhein Fire and the London Monarchs.

On 29 March 2007, Bicknell resigned, citing health issues as the reason. He was replaced by offensive coordinator Vince Martino.

On 23 June 2007, the Sea Devils won their first World Bowl championship with a 37–28 victory over the defending champion Frankfurt Galaxy. It was also their last, as NFL Europa disbanded almost immediately following the game. As a result, the Sea Devils are the last team to win a WLAF/NFL Europe/NFL Europa game ever.

Previously, Thomas Herrion, an offensive tackle allocated to the team by the San Francisco 49ers, died after a preseason game against the Denver Broncos in August 2005.

An unrelated team of the same name has played since 2021 in the new European League of Football.
