Lake Mácha is an artificial lake in the Liberec Region of the Czech Republic, near Doksy and Bezděz Castle.
During Cenozoic a large lake existed at this site. During the last Ice Age the lake drained away, leaving only a peat bog. Between 1366 and 1367 Charles IV ordered a large pond to be established here.
Its older name was Velký rybník or Hirschberský rybník. Its current name was established after 1945, officially since 1961. The name refers to the romantic poet Karel Hynek Mácha.
