Pierre Léna, born on 22 November 1937 in Paris, is a French astrophysicist.

In 1973, Léna was one of the scientists aboard the Concorde 001 during its flight in the shadow of a solar eclipse.

Aboard, he conducted an experiment studying the F-corona (dust particles left over from comets in the sun's corona).

Léna later published a book, Concorde 001 et l’ombre de la Lune (2015), about his experience with the flight.
