"When the Lovelight Starts Shining Through His Eyes" is a song written by Holland–Dozier–Holland and recorded in 1963 by Motown singing group The Supremes. It is notable as the Supremes' first Billboard Hot 100 Top 40 recording, following seven previous singles between January 1961 and September 1963 which failed to enter the Top 40. The single is also notable as the first Supremes single written and produced by Holland–Dozier–Holland, who had previously created hits for Martha and the Vandellas and Mary Wells.

The Supremes were an American girl group and a premier act of Motown Records during the 1960s. Founded as the Primettes in Detroit, Michigan, in 1959, the Supremes were the most commercially successful of Motown's acts and the most successful American vocal band, with 12 number-one singles on the Billboard Hot 100. Most of these hits were written and produced by Motown's main songwriting and production team, Holland–Dozier–Holland. It is said that their breakthrough made it possible for future African-American R&B and soul musicians to find mainstream success. Billboard ranked the Supremes as the 16th greatest Hot 100 artist of all time.
