Östanbäck Monastery, Lutheran Benedictine monastery near Sala, Sweden.

Östanbäck Monastery is a Lutheran Benedictine monastery outside Sala in Västmanland. Its main building was erected as a school in 1876 and later housed a mattress factory before the brothers converted it; the monastery building, with chapel, cells and kitchen, was taken into use in 1972 and consecrated on 20 July 1975. A separate church, Enhetens kyrka, opened in 2012.

Four theology students from Lund and Uppsala universities established the Holy Cross Fraternity in 1960, leading to the monastery's founding in 1970. The community moved to its current buildings as it grew.

The monks pray the Divine Office seven times a day and celebrate Mass daily, following the Rule of Saint Benedict. Their post-nominal letters O.S.B. reflect this Benedictine affiliation, and the abbot is invited as an observer to the Benedictine abbots' conferences in Rome. The community also supports itself by making candles, including Paschal candles.

The grounds are accessible to visitors and allow observation of candle production in the workshop along with participation in prayer times. It helps to check ahead for visiting hours and what activities take place.

The monastery operates a candle workshop producing specialized candle types, including distinctive Paschal candles with custom designs. This production is part of the monks' economic activity and the monastery's self-sufficiency.
