The Lioré et Olivier H-190 was a biplane flying boat aircraft designed and produced by the French aircraft manufacturer Lioré et Olivier.

Developed as a passenger transport, various versions of the H-190 were also developed, including catapult-ready mail planes intended to be launched from transatlantic ocean liners and coastal patrol aircraft.

The sole LeO H-194 was flown by Marc Bernard together with a CAMS 37 flown by René Guilbaud in a long-distance expeditionary flight across Africa in late 1926. They covered 28,000 km (17,000 mi) in three months, covering Morocco, Mali, Nigeria, Belgian Congo, Mozambique and Madagascar.
