Peter Christian Lutkin (1858–1931) was an American composer, conductor, and educator, primarily known for his contributions to choral music and hymnody. He was a prominent figure in the late 19th and early 20th centuries, associated with the sacred music genre. Lutkin served as the director of music at the University of the South in Sewanee, Tennessee, where he significantly impacted choral education. His most notable work is the "The Lord Bless You and Keep You," a choral benediction that remains popular in church settings and choral repertoire. He also published several collections of hymns and anthems, contributing to the development of American choral literature. Lutkin's impact on music is evident in his emphasis on accessible choral works that blended traditional harmonies with contemporary idioms of his time. His compositions are characterized by their lyrical melodies and rich harmonies, appealing to both amateur and professional choirs. Though not as widely recognized today, his work laid the groundwork for future generations of composers in the sacred music tradition.
