The Baptist Convention of Costa Rica (Convención Bautista de Costa Rica) is the largest Baptist group in Costa Rica.
In 1888, the Jamaica Baptist Missionary Society sent J. H. Sobey to labor in Costa Rica. Four Baptist churches formed the Baptist Convention of Costa Rica in 1947. This convention labored in cooperation with the Southern Baptist Convention until a dispute arose in 1980 and the relationship was severed. In 1981, those wishing to continue cooperation with the Southern Baptist Convention organized the National Union of Baptist Churches.
In 1995, the Baptist Convention of Costa Rica had 24 churches with about 3500 members.
