Roslags-Bro Church (Swedish: Roslags-Bro kyrka) is a medieval Lutheran church in the Archdiocese of Uppsala in , Sweden. It was built during the middle of the 13th century by an important sea-route, since disappeared as a consequence of the post-glacial rebound. Immured in the church is a runestone from the 11th century.
When Roslags-Bro church was built in the 13th century it was located by a once important sea-route which has since disappeared as a consequence of post-glacial rebound. Immured in the church is a runestone from the 11th century raised in memory of a man who was killed in Estonia across the Baltic Sea (runestone U533). Throughout the Middle Ages, the church was one of the most important churches in Roslagen, and one of the first stone churches in the area. Archbishop Nathan Söderblom still referred to the church as "the Cathedral of Roslagen".
Several details, notably the extensive use of sandstone from Gotland and the church's triumphal cross and baptismal font coming from there, indicate the workshop building the church might have come from Gotland.
During the 15th century, the choir was added and the ceiling further vaulted and decorated with frescos. The latter have never been painted over and so retain much of their original brilliance. It has been suggested that Sten Sture the Elder might have commissioned them.
