The Mission Sui Iuris of Funafuti (Latin: Missio Sui Iuris Funafutinum) is a Catholic Latin mission sui juris (pre-diocesan missionary jurisdiction) in Tuvalu, Polynesia.
It depends on the Congregation for the Evangelization of Peoples, yet it is exceptionally not exempt, but instead is a suffragan of a Metropolitan archdiocese. Since 21 March 2003, that metropolitan see has been the Archdiocese of Suva; until that date, it had been a different see, i.e., the Archdiocese of Samoa-Apia.
Its only place of worship is Teone Church in Vaiaku, on Fongafale island in Tuvalu.The current Superior is Reynaldo B. Getalado, M. S. P., appointed in 2014.
The Diocese of Tarawa, Nauru and Funafuti was split on 10 September 1982 into the Diocese of Tarawa and Nauru and the Mission Sui Iuris of Funafuti.
