Webu Sayadaw (Burmese: ဝေဘူ ဆရာတော်, pronounced [wèbù sʰəjàdɔ̀]; 17 February 1896 – 26 June 1977) was a Theravada Buddhist monk, and vipassanā master, best known for giving all importance to diligent practice, rather than scholastic achievement.

Webu Sayadaw was born to Daw Kyin Nu and U Lu Pe in 1896 in British Burma near Khin U township in modern-day Sagaing Division.

He said that by working with this practice to a very deep level of concentration, one is able to develop Vipassanā (insight) into the essential characteristics of all experience: anicca (impermanence), anatta (egolessness) and dukkha (unsatisfactoriness).

Webu Sayadaw was famous for his unflagging diligence in meditation and for spending most of his time in solitude.

Webu Sayadaw stayed in upper Burma, dividing his time among three meditation centres in a small area.
