Ambrosio Kibuuka was a Catholic martyr from Buganda who was executed for his religious convictions in 1886. Born around 1868, he served as a page in the royal palace of King Mwanga II. After converting to Christianity, he was baptized by the missionary Siméon Lourdel in late 1885. During a period of intense persecution, he was arrested and eventually taken to Namugongo, where he was burned alive alongside other Christian converts.
