John Parry Senior was an early Welsh convert to The Church of Jesus Christ of Latter-day Saints and was the first musical conductor of the Mormon Tabernacle Choir.
Parry was born in Newmarket (now known as Trelawnyd), Flintshire, in north-east Wales.
Upon arriving in Council Bluffs, Iowa, on May 17, 1849 Mary Parry died of cholera. After the conference, church president Brigham Young invited Parry to formally organize a church choir that could provide music at future church conferences. Parry was the conductor of the choir until 1854, when he was succeeded by Stephen Goddard.
Like many early Latter Day Saints, Parry practiced plural marriage.
Parry was the father of 12 children. Parry died in Salt Lake City and was buried there.
