Dieter Müller (born Dieter Kaster on 1 April 1954) is a German former footballer who played as a forward. He achieved his greatest success playing for 1. FC Köln in the Bundesliga in the late 1970s. He scored 177 goals in 303 games in the German league, including 6 goals in one game in August 1977, a record that still stands. He also played 12 times for West Germany from 1976 to 1978, scoring 9 goals.
Müller played and scored in the UEFA Euro 1976 final, which West Germany lost on penalties to Czechoslovakia. He was again in the national team in the 1978 FIFA World Cup, though the campaign ended in disappointment when West Germany, the defending champions, did not qualify for the tournament's later stages. In his spell with 1. FC Köln he set a record for the most goals scored by a player in a single Bundesliga match. On 17 August 1977, he tallied six goals (scoring in the 12th, 23rd, 32nd, 52nd, 73rd and in the 85th minute) in Köln's 7–2 victory over Werder Bremen in front of a crowd of 19,000 at Köln's Müngersdorfer Stadion. However, since television cameramen were on strike on that day, there are no known film of Müller's goals. He was crowned Bundesliga topscorer that season (24 goals in 33 games), as he had the season before (34 goals in 34 appearances).
After he left Köln, he played for several seasons in France and Switzerland, before returning to West Germany.
Müller is the son of Heinz Kaster, who played as a defender for FC St. Pauli and Kickers Offenbach in the early 1950s. The striker had already been a schoolboy international, when his stepfather's adoption turned his surname into Müller.
