You Shook Me is a blues song written by Willie Dixon and first recorded by Muddy Waters. It was later recorded by various rock musicians, including Jeff Beck on his album Truth and most famously by the rock group Led Zeppelin on their debut album. On the Zeppelin recording John Paul Jones double tracked the organ and the electric piano.

Since the Zeppelin version was released in 1969, one year after Beck's, he accused them of stealing his idea. The Zeppelin version is one of the few songs to showcase the talents of all four members, and the band played it frequently at their early live shows. It was the first of their songs to feature the call-and-response blues style of music.

Led Zeppelin did not originally credit Dixon for the song. He sued, won a substantial amount of money, and his name was placed in the credits.
