Boleslaw Szczeniowski (20 July 1898 – 1985) was a Canadian aeronautical engineer and composer of Polish descent.
A graduate of the school of engineering at Lviv Polytechnic, Szczeniowski made a living as an engineer in Montréal.
He published two books: Theory of the siphon jet (published by the National Advisory Committee for Aeronautics, 1955) and Theoretical analysis of combustion gases (Montreal, 1946).
As a composer and musician, Szczeniowski was largely self-taught.
He composed a significant amount of vocal music and works for solo piano and a small amount of chamber music.
