The International Wrestling Alliance (IWA) World Heavyweight Championship (IWA世界ヘビー級王座, IWA Sekai Hebī-kyū Ōza) was a professional wrestling world heavyweight championship of the Japanese professional wrestling promotion known as International Wrestling Enterprise (国際プロレス興行, Kokusai Puroresu Kogyō). It was the first Japanese heavyweight title to be billed as a World title, and in the 1970s and early 1980s it was one of the most important titles in Japan. The title died with the promotion in 1981 but was later revived by Goro Tsurumi for his independent Kokusai Promotion.

There have been eighteen reigns between twelve wrestlers, and three vacancies.
