Manaku (c. 1700–1760) was an Indian painter from the Guler State, in modern-day Himachal Pradesh, who specialized in Pahari painting.
After his death, he was mostly forgotten, and overshadowed by his much-celebrated younger brother Nainsukh. But today he is recognized 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.
