Reid Neibaur Nibley (5 January 1923 – 25 February 2008) was an American pianist, composer and music educator.
Nibley was raised mainly in the Los Angeles area, where he was friends with Ray Bradbury, also a youth at the time.
They would jointly write the music and scripts of roadshow productions of area youth groups of The Church of Jesus Christ of Latter-day Saints.
Nibley married Marjorie McBride in 1947 and they had six children: Stephen, Breta, Richard, Garn, Virginia, and Jonathan.
Nibley's hymn "I Know My Father Lives" is in both the Primary Children's Songbook and the 1985 hymnal of the Church of Jesus Christ of Latter-day Saints.
