William Norris Powell (June 3, 1952 – January 28, 2009) was an American musician and the keyboardist of southern rock band Lynyrd Skynyrd from 1972 until his death in 2009.

The band's popularity soared in 1974 with their follow-up album, Second Helping, which featured their highest-charting single, "Sweet Home Alabama".

During the time between the plane crash and the Lynyrd Skynyrd reunion in 1987, Powell joined the Christian rock band Vision in 1984.

During the concerts, Powell spoke about his newfound Christianity; messages that were also delivered via two bonus tracks included on the album Mountain in the Sky.

His death inspired countless tributes, in and out of the Southern rock community and extending across the country-music world, where he had many friends and admirers.

The music he had recorded with Vision was played exclusively at a private memorial service, and Kid Rock sang a tribute.

He was survived by his wife Ellen, sons Brandon and Joel, daughters Layla, Ashley, and Maggie, brother Rick, and sister Donna.
