Chrysostome Liausu, SS.CC., (born Charles-Auguste Liausu; 17 March 1807 – 5 September 1839) was a French Catholic priest of the Congregation of the Sacred Hearts of Jesus and Mary, a religious institute of the Roman Catholic Church.
Liausu joined the Congregation of the Sacred Hearts of Jesus and Mary in 1825 and took the name Jean-Chrysostome, presumably after Saint John Chrysostom.
[4] Liausu was part of a small group of French Picpus missionaries sent by Pope Gregory XVI and the Propaganda Fide to convert the natives of Eastern Oceania.
[5][1][6] In 1834, Liausu and François Caret, Honoré Laval and Columba Murphy arrived in Valparaíso from Bordeaux.
[7] Although initially faced with hostility from Mangareva's King Maputeoa, the three Catholic missionaries managed to land on a small island where the local chief and later Maputeoa's uncle Matua gave them support to learn the Mangareva language and the islanders learned about Christianity.
