Big Kenny, American singer-songwriter and guitarist
William Kenneth Alphin (born November 1, 1963), best known by his stage name Big Kenny, is an American country music singer. He and John Rich comprise the duo Big & Rich, who recorded four studio albums and charted fifteen singles on the Billboard Hot Country Songs chart.

Before Big & Rich, Big Kenny recorded a solo album Live a Little for Hollywood Records in 1999 (although it was not released until 2005) and fronted a band called luvjOi. He has also written or co-written several of Big & Rich's songs with Rich, as well as singles for Gretchen Wilson, Jason Aldean, McBride & the Ride, and Tim McGraw. His first solo single, "Long After I'm Gone," was released to country radio on August 3, 2009, from the album The Quiet Times of a Rock and Roll Farm Boy. In 2010, his third solo album, Big Kenny's Love Everybody Traveling Musical Medicine Show Mix Tape, Vol. 1, was released but did not produce any singles.

Big Kenny also took a stab at acting when he starred in the independent film The Frontier Boys by director John Grooter.
