Paul "Wix" Wickens (born 27 March 1956) is an English singer-songwriter, multi-instrumentalist, composer, and record producer. In a career spanning more than 40 years, Wickens has worked with artists including Paul McCartney, Nik Kershaw, Bob Dylan, Joni Mitchell, Bon Jovi, Edie Brickell and many others. Wickens has also been a member of McCartney's touring band since 1989.

In the early 1980s Wickens was a member of Woodhead Monroe, a band that issued two singles distributed by Stiff, "Mumbo Jumbo" and "Identify."

Wickens began touring with Paul McCartney in 1989. As of then, he has appeared on many of McCartney's albums and DVDs, and has become the musical director for many of McCartney's tours. He continues to tour with McCartney (as his keyboardist, occasional guitarist and backing vocalist), and of the four musicians in McCartney's touring band, he has worked with McCartney the longest by a considerable margin.
