The Reverend Frederick Scotson Clark (Southwark, 16 November 1840 – London, 5 July 1883) was an English organist and composer.
He married Catherine Eliza Brown - it turned out to be an unhappy marriage - and they moved to Leipzig, where he continued his musical studies under Reinecke and Richter and officiated at an English chapel there.
He was chosen to represent English organists at the Paris Exposition of 1878, where he won a gold award.
Kathleen Scotson Clark (1870-1959) became headmistress of Allerton High School in Leeds.
It was his son, the artist George Frederick Scotson-Clark (1872-1927), who used the hyphenated form of the surname.
