Gerleve Abbey, Benedictine monastery in Billerbeck, Germany.

Gerleve Abbey is a Benedictine monastery in Billerbeck, North Rhine-Westphalia. Its neo-Romanesque church, designed by Wilhelm Rincklake and begun in 1901, has a 42-metre tower and a rose window on its right facade. Two long wings with rows of rectangular windows enclose a four-sided courtyard in front of the church.

The monastery was founded in 1899 on a farmstead and experienced disruption during World War II when the monks were expelled in 1941 by the National Socialists. After the war, the community returned and rebuilt monastic life here.

The monks sing the Liturgy of the Hours four times a day in the convent church, and visitors are welcome to join. Since 1918 Gerleve has been a centre of the liturgical movement in north-west Germany, and the community kept up Gregorian chant after the Second Vatican Council; its schola has released a CD of traditional chant. Free public lectures and concerts are held several times a year under the name "Forum Gerleve".

Visitors can stay in two guest houses that provide simple accommodation in a quiet setting. The grounds are easy to explore on foot and the church is accessible for services and visits.

The abbey church holds a late-Romanesque crucifixion group from northern Spain, carved in the early 13th century, with life-size figures of Christ, Mary and John, hung in the crossing since 2005. In the north tower, a gilded carved wooden Heart of Jesus altar made by sculptor Heinrich Seling in 1912 stands in its own chapel.
