Evangelische Pfarrkirche Haiger, Protestant parish church in Haiger, Germany.

The Evangelische Pfarrkirche is a Protestant church building in Haiger with traditional German architectural features. The structure includes a distinctive bell tower and stands in the town center.

A church was first documented in 914, when King Conrad I granted a baptismal church, the Hof Heiger and market rights to the Walpurgisstift Weilburg. The west tower's oldest sections date to the 11th century, the choir with its wall paintings to 1460–1494, and the three-aisled hall to the early 16th century. The Reformation was introduced in Nassau-Dillenburg in the 1530s, and around 1578 the parish adopted the Reformed confession, whose ban on images led to the frescoes being whitewashed around 1585.

The church's name origin is tied to Haiger's status as a mother church and seat of a deanery that once covered parishes across the Dillenburg district. The late Gothic wall paintings in the choir, financed around 1485–1490 by the last knights Hermann and Jost von Haiger, were whitewashed around 1585 under Reformed iconoclasm and only uncovered again in 1905 by Cologne church painter Wilhelm Batzem.

The church is located in the center of Haiger and is easily accessible on foot. Visitors can explore the building anytime but should check opening hours and service schedules beforehand.

The bell tower is a distinctive feature of the town's appearance and can be seen from many points in Haiger. This visibility made the church an important landmark for residents across generations.
