IHI公司（英语：IHI Corproation，日语：株式会社IHI），前称「石川岛播磨重工业」（英语：Ishikawajima-Harima Heavy Industries），是日本一家重工业公司。

IHI公司起源于1853年（嘉永6年），当时江户幕府指令水户藩主德川齐昭下令于江户隅田川河口的石川岛（位于现在东京都中央区佃二丁目）建设造船厂，成为「石川岛造船厂」。一战后开始涉足汽车及飞行器制造业务，二战时参与建造军舰及飞行器。二战后透过并购继续壮大，2007年更名为株式会社IHI。

Ihi, Ehee or Bel Marriage (Nepal Bhasa:ईही) (Bel bibaha) is a ceremony in the Newar community in Nepal in which pre-adolescent girls are "married" to the bel fruit (wood apple), which is a symbol of the god Vishnu, ensuring that the girl becomes and remains fertile. It is believed that if the girl's husband dies later in her life, she is not considered a widow because she is married to Vishnu, and so already has a husband that is believed to be still alive.
