Ven. U Wisara (Burmese: ဦးဝိစာရ, pronounced [ʔú wḭsəɹa̰], Pali: Vicāra; 24 April 1889 – 19 September 1929) was a Burmese Buddhist monk who died in prison after a 166-day hunger strike against the colonial British rule in Burma. The monk had been repeatedly imprisoned and tortured by the colonial government for "inciting sedition", and forced to wear plain clothes and abandon religious observances. His "ultimate sacrifice profoundly moved many Burmese who not concerned themselves with politics before", and galvanized the nascent independence movement. The monk is commemorated today with the , a major avenue in Yangon, and the U Wisara Monument in Yangon.
