"You Are in My System" is a 1982 song recorded by the American band System. It was written by Mic Murphy and David Frank and released in August 1982 by Mirage Records. The song is also included on their debut studio album Sweat (1983). It is one of the duo’s most recognizable songs and a favorite of many System fans worldwide.

In 1983, the song was covered by the English rock singer Robert Palmer. This version, which was produced by Palmer and remixed by Dominique Blanc-Francard, reached No. 78 on the Billboard Hot 100 chart and No. 33 on the Mainstream Rock chart. It was recorded after the rest of the Pride album had been completed when Palmer heard the original 12" promo copy at the famous Paris private night club l'Elysées Matignon. He quickly flew back to cut it as an extra track, and it was recorded within 24 hours. He had even persuaded David Frank to play on it himself.
