Mario Pascal (31 May 1896 – 6 November 1949) was an Italian applied mathematician, specializing in fluid mechanics and aerodynamics.
Mario Pascal studied mathematics at the University of Naples, where he received his laurea in 1919.
He was an assistant in rational mechanics to Roberto Marcolongo and then became at the Istituto Superiore Navale a libero docente in rational mechanics and then a professore incaricato.
His death was due to an illness contracted during WW I.
He dealt almost exclusively with mechanics, especially fluid mechanics, attempting with very limited success to extend the Kutta-Joukowski theorem to three dimensions of space.
