Richard Wayne Mullins (October 21, 1955 – September 19, 1997) was an American Contemporary Christian Music singer and songwriter born in Richmond, Indiana. He had two sisters and two brothers.

Mullins was best known for his worship songs "Awesome God" and "Step by Step", both of which have been embraced as modern classics by many Christians. Some of his albums were also considered among Christian music's best, including Winds of Heaven, Stuff of Earth (1988), The World As Best As I Remember It, Volume One (1991) and A Liturgy, A Legacy, & A Ragamuffin Band (1993). His music has been covered by many artists, including Caedmon's Call, Five Iron Frenzy, Amy Grant, Carolyn Arends, Jars of Clay, Michael W. Smith, John Tesh, Chris Rice, Rebecca St. James, and Third Day.

Rich Mullins is also remembered for his devotion to the Christian faith. He was heavily influenced by St. Francis of Assisi (1181–1226). In 1997, he composed a musical called Canticle of the Plains, a retelling of the life of St. Francis set in the Old West.
