Eckhard Dagge (27 February 1948 – 4 April 2006) was a German professional boxer who competed in the super welterweight division.

Eckhard Dagge was Germany's second world champion, after Max Schmeling, holding the World Boxing Council Light Middleweight title from 1976 to 1977. Dagge also held German National and European titles, during his ten-year career.

Dagge was born in Berlin, West Germany, in 1948. He learned how to fight in the bars and taverns of Hamburg. He would later embark on an amateur career, in which he won 66 out of 80 bouts, before falling short of making the 1972 Olympic Team. Dagge turned professional in 1973, at the age of 25.

Dagge would win the German Middleweight title, in his 6th bout. Dagge would follow up with wins over notable, but faded fighters Denny Moyer and Manuel González. In 1974, Dagge challenged Jose Manuel Duran for the European Light Middleweight title, losing by 11th-round TKO. He came back the next year however, and stopped Duran in the 9th round, to win the title. He would defend the title once, before losing it by decision to Vito Antuofermo.

Dagge earned a title shot against WBC Light Middleweight champion Elisha Obed on 17 June 1976. Dagge pulled off a stunning upset of Obed, winning by 10th-round TKO, to win the title in Berlin. Dagge was scheduled to defend his title against Sugar Ray Seales. However Seales pulled out a of the fight and former champion Emile Griffith stepped in as a replacement. The result was Dagge winning a controversial majority decision. He followed this up with a draw over England's Maurice Hope,^[1] a future world champion. Dagge then faced Australia-based Italian Rocky Mattioli on 6 August 1977, and was knocked out in the 5th round. Dagge would win six more bouts over lesser opposition until he was stopped by Brian Anderson in 1981, he retired from the ring shortly thereafter.

Dagge had a reputation as a wild man during his career and afterwards, as he struggled with alcoholism. Dagge worked with Universum after his pro career ended, training Dariusz Michalczewski, Michael Loewe, and Mario Schiesser. However, he was dismissed from his job as a manager in 1994, due to absenteeism and his problems with alcoholism. Dagge died on 4 April 2006 in Hamburg, Germany, after a battle with cancer.^[2]
