Manaku of Guler or Manaku was an Indian painter from the Guler State, in modern-day Himachal Pradesh. After his death he was mostly forgotten and overshadowed by his much-celebrated younger brother Nainsukh. But today he is recognised as an exponent of Pahari style of painting, much like his brother. The rediscovery of Manaku has been a result of research efforts by art historians like B. N. Goswamy.
Like Nainsukh, Manaku almost never signed his works, and only four extant works carry his signature.
