The Protestant Church in East Timor is a Reformed Protestant denomination in East Timor.
During Portuguese colonial rule in East Timor, which lasted until the country was annexed by Indonesia in 1975, Protestantism was suppressed. The Protestant Christian Church in East Timor came into being in 1979. Synod was established in 1988; that is the founding date of the denomination. Membership grew from 6,668 to 34,625 in 1996. In 1998 it joined the World Communion of Reformed Churches and the World Council of Churches.
The denomination publishes a mounthy magazine, Tatoli, which means "message". It has a presbyterian church government.
The church maintains a relationship with the American United Church of Christ.
Atauro Island is one of the few areas of the country where Protestants outnumber Catholcis. Most inhabitants of Atauro belong to a Dutch Reformed Calvinist Church.
