Robert Bloch (26 April 1888 – 7 March 1984) was a French racing driver who, along with André Rossignol, won the 1926 24 Hours of Le Mans for French manufacturer Lorraine-Dietrich.

Bloch had been part of Lorraine-Dietrich's racing team since the inaugural 24 Hours of Le Mans in 1923, finishing this edition, but struggled to complete the distance over the next two years.

Bloch missed Le Mans in 1927 after Lorraine-Dietrich chose not to enter a team, but Bloch was hired by Charles Terres Weymann in 1928 to drive his privately entered Stutz Blackhawk.

Bloch, with co-driver Édouard Brisson, finished the race second overall behind the factory Bentley team.
