Reginald Le Borg (11 December 1902 – 25 March 1989) was an Austrian film director. He directed 68 films between 1936 and 1974. He was born in Vienna, Austria as Reginald Grobel and died in Los Angeles, California from a heart attack.

Although he worked in a variety of genres, he is perhaps best remembered today for the series of low-budget horror films he made at Universal Studios in the 1940s. His most expensive and also most successful film was San Diego, I Love You (1944) featuring Buster Keaton in a supporting role.
