Basilica of St. John the Baptist, Saarbrücken, Catholic basilica in Saarbrücken, Germany

The Basilica of St. John the Baptist is a baroque church near the St. Johanner Markt in Saarbrücken, built to plans by Friedrich Joachim Stengel. It replaced a chapel demolished in 1754; the new building was erected between 1754 and 1758. The church is listed as an individual monument in the Saarland monument register and belongs to the Diocese of Trier.

A chapel dedicated to John the Baptist stood on this site by the 7th century, first documented in 1325; the medieval chapel was rebuilt in 1608–1615 and demolished in 1754. Friedrich Joachim Stengel built the present baroque church between 1754 and 1758. Pope Paul VI raised it to minor basilica in 1975, and the interior was redone in baroque style between 1972 and 1975.

The church takes its name from John the Baptist, to whom the medieval chapel on this site was dedicated; the parish celebrates its patronal feast on 24 June, the feast of his birth. The present building belongs to the Diocese of Trier and is listed as an individual monument in the Saarland monument register. Organ concerts are held alongside Catholic Mass.

The church stands just off the St. Johanner Markt, a short walk from the market square in Saarbrücken's centre. It belongs to the Diocese of Trier and is listed as an individual monument in the Saarland monument register. Besides Catholic masses, organ concerts are held there regularly.

The interior underwent substantial restoration work between 1972 and 1975 to recover the original baroque elements in their full splendor. This careful renovation work preserved decorative details that might otherwise have been lost and returned the space to its historical appearance.
