Raymond Thomas (29 December 1941 – 4 January 2018) was an English musician, flautist, singer, founding member and composer in the English progressive rock band the Moody Blues. His flute solo on the band's 1967 hit single "Nights in White Satin" is regarded as one of progressive rock's "defining moments." In 2018, Thomas was posthumously inducted into the Rock and Roll Hall of Fame as a member of the Moody Blues.
