Johann Jakob Schütz (1640–1690) was a German lawyer, Pietist, and hymn writer, best known for his hymn "Sei Lob und Ehr dem höchsten Gut" (Sing Praise to God Who Reigns Above).

Born on September 7, 1640, in Frankfurt am Main, Schütz studied law at the University of Tübingen and became a respected lawyer in his hometown. He was a prominent figure in the early Pietist movement, a reform movement within Lutheranism that emphasized personal piety and spiritual renewal. Schütz was deeply influenced by Philipp Jakob Spener, a leading figure of Pietism, and often hosted Pietist gatherings in his home.

Schütz's most enduring contribution is his hymn "Sei Lob und Ehr dem höchsten Gut," written around 1675. This hymn expresses deep gratitude and praise to God for His providence and faithfulness. It quickly gained popularity within Pietist circles and later spread throughout German Protestantism. The hymn's text is characterized by its strong affirmation of trust in God's goodness and its call to joyful praise. It has been translated into numerous languages, with the English version "Sing Praise to God Who Reigns Above" being particularly well-known.

His work is often found in various hymnals and collections, reflecting its lasting theological and spiritual significance. The hymn's text is frequently paired with the traditional 16th-century tune "Mit Freuden zart," which was harmonized by Maurice F. Bell in 1906, helping to popularise the melody in English-speaking worship.
