The Boeing 929 Jetfoil is a passenger-carrying, waterjet-propelled hydrofoil by the Boeing Company.

Boeing adapted many systems used in jet airplanes for hydrofoils. Robert Bateman led development. Boeing launched its first passenger-carrying waterjet-propelled hydrofoil in April 1974. It could carry from 167 to 400 passengers. It was based on technology developed for the U.S. Navy patrol hydrofoil Tucumcari, and shared technology with the Pegasus-class military patrol hydrofoils. The product line was licensed to the Japanese company Kawasaki Heavy Industries.
