Dr. Jiro Horikoshi (堀越 二郎, Horikoshi Jirō^?, 22 June 1903 – 11 January 1982) was the chief engineer of many Japanese fighter designs of World War II, including the Mitsubishi A6M Zero fighter.

Dr. Jiro Horikoshi was born near the city of Fujioka, Gunma Prefecture, Japan, in 1903. Horikoshi graduated from the newly established Aviation Laboratory (Kōkū Kenkyūjo) within the Engineering Department of the University of Tokyo, and started his career in Mitsubishi Internal Combustion Engine Company Limited, which later became Mitsubishi Heavy Industries, Nagoya Aircraft Manufacturing Plant.

Jiro Horikoshi's first work was the flawed Mitsubishi 1MF10, an experimental aircraft that never passed the prototype stage after some flight tests. However, lessons learned from this design led to the development of the far more successful Mitsubishi A5M (Allied codename "Claude") which entered mass production in 1936.

Some time later Horikoshi and his team at Mitsubishi were asked, in 1937, to design Prototype 12 (corresponding to the 12th year of the Showa era). Prototype 12 was completed in July 1940, and it was accepted by the Imperial Japanese Navy. Since 1940 was the Japanese year 2600, the new fighter was named as "Model 00" or "Zero" or A6M Zero, in Japan also known as the "Rei-sen" (literally meaning "zero fight", shortened for Model zero fighter airplane). Subsequently, he was involved in many other fighters manufactured by Mitsubishi, including the Mitsubishi J2M Raiden (Thunderbolt) and the Mitsubishi A7M Reppu (Strong Gale).
