“Prevost” could refer to several different people or brands, and they are not all the same age.

Here are the main possibilities people mean when they ask “how old is Prevost” right now (February 2026):

  • Pope Leo XIV (born Robert Francis Prevost) – He was born on 14 September 1955 in Chicago. That makes him 70 years old in 2026.
  • Daniel Prévost (French actor/comedian) – He was born on 20 October 1939. That makes him 86 years old in 2026.
  • Prevost as a company/brand name – Industrial and bus-related companies called Prevost have founding dates and histories, but they are organizations rather than a person with an “age” in years like a birthday.

Because your question only says “how old is prevost,” it’s ambiguous. If you tell me whether you meant the pope (Robert Francis Prevost), the French actor Daniel Prévost, or a company named Prevost, I can give you a precise age for that specific one.
