Markus Eichler (born 18 February 1982 in Varel) is a German former professional road bicycle racer.

In 2011, he had originally signed with an Australian team called Pegasus, but that team failed to secure a UCI license of any kind, leaving its riders to need to sign elsewhere. Eicheler instead rose for Team NSP.

Eichler left NetApp–Endura at the end of the 2013 season, and joined Team Stölting for the 2014 season.
