The Toyota HiAce (Japanese: トヨタ・ハイエース, Toyota Haiēsu) (pronounced as “High Ace”) is a light commercial van produced by the Japanese automobile manufacturer Toyota. First launched in October 1967, the HiAce has since been available in a wide range of body configurations, including a minivan/MPV, minibus, panel van, crew van, pickup truck, taxi and ambulance. In Japan, the HiAce is exclusive to Toyopet Store locations.

The HiAce was primarily designed as a commuter vehicle, able to transport up to 8 people. With this goal in consideration, the HiAce exterior dimensions and engine displacement were in compliance with Japanese government regulations so as to encourage sales, and accommodate the most passengers by utilizing a cover body style, with the engine installed underneath and between the front passengers. It was a smaller alternative to the larger Toyota Coaster minibus and was introduced to Japan after the 1950 Volkswagen Transporter, and the 1961 Chevrolet Greenbrier cabover vans. It was introduced in the same year as the much smaller Toyota MiniAce, which was based on the Toyota Publica, a predecessor to the Toyota Corolla.
