Thomas Christopher Kelly (5 December 1917 – 31 March 1985) was an Irish composer, teacher and conductor.
T. C. Kelly was born in Wexford and studied with John F. Larchet at University College Dublin (BMus, 1943).
After having spent a period as organist and choirmaster in Newry, County Down, he was appointed music master at Clongowes Wood College in County Kildare (1952–1985), a position which involved teaching, playing organ in the boys' chapel and conducting the school choir and orchestra.
Kelly's prolific output consists mainly of skilful arrangements of Irish traditional music for orchestra, mixed choir or small instrumental ensembles such as violin and piano.
Although mainly known as a composer of miniatures, he also wrote a three-movement piano concerto (1960) and three full-scale congregational masses.
