Klaus Eichler (11 October 1939 – 24 January 1994) is a former party and sporting official in East Germany.
Eichler began his career in government in the 1960s, when he became actively involved in district management of the Free German Youth (FDJ) and the ruling Socialist Unity Party, eventually becoming a member of the FDJ's Central Council.
In 1984 Eichler became the vice-president of the Deutscher Turn- und Sportbund (DTSB), the main governing body for sports in East Germany.
Upon then-incumbent President Manfred Ewald's retirement for health reasons in 1988, Eichler was approved as his successor by Erich Honecker and Egon Krenz.
Eichler held this post until he and all other members of the DTSB's executive committee resigned at the end of 1989.
