ROHM Semiconductor (ローム株式会社 Rōmu Kabushiki-gaisha) is a Japanese electronic parts manufacturer based in Kyoto, Japan. ROHM was incorporated as Toyo Electronics Industry Corporation by Kenichiro Sato (佐藤 研一郎) on September 17, 1958.

The company was initially known as R.ohm which was derived from R, for resistors, the original product, plus ohm, the unit of measure for resistance.

The name of the company was officially changed to ROHM in 1979 and then changed again to ROHM Semiconductor in January 2009.

When ROHM was established, resistors were its main product. Later, the company began manufacturing semiconductors. IC's and discrete semiconductors now account for about 80% of ROHM's revenue.

Through 2012, ROHM was among the top 20 semiconductor sales leaders.
