John Sing Tang (1913 – December 3, 1987) was a modernist architect from Arizona.
He received his degree in architecture from Rice University in 1944.
Though many of his commercial works have been demolished he is still highly regarded architect in Arizona.
His Helsing's Coffee Shop and Melrose Bowling Alley designs of the late 1950s are considered exceptional examples of Googie Architecture (both now demolished).
Tang died in 1987 at Saint Joseph's Hospital in Phoenix at the age of 74.
