Johann Valentin Eckelt (born 1730, date of death unknown) was a German composer and organist, primarily known for his contributions to the sacred music genre during the late Baroque and early Classical periods. He served as an organist at various churches in Germany, which influenced his compositions focused on liturgical settings. Eckelt's notable works include a collection of chorale settings and cantatas that reflect the theological and musical trends of his time. His compositions often displayed intricate counterpoint and melodic lines, drawing on the traditions of Johann Sebastian Bach and other contemporaries. While Eckelt may not be as widely recognized as some of his contemporaries, his work contributed to the development of church music in Germany and highlighted the transition from Baroque complexity to the more homophonic textures that characterized the Classical period. His influence can be seen in the way subsequent composers approached sacred music, blending traditional forms with emerging styles. Overall, Eckelt's legacy lies in his role as a bridge between the Baroque and Classical traditions in sacred music.
