Willard Palmer Harris (October 28, 1916[1] – August 21, 1973)[2] was an American jazz trombonist.

[1] Early in his career, Harris performed with Benny Goodman, Charlie Barnet, and Eddie Condon.

[2] Together with Flip Phillips, he became a stalwart of Benny Goodman's group in 1959,[2] although it has been said that Goodman was frequently irritated at Harris because of Harris' indifferent approach to "sight-reading," the skill of playing previously unseen written music with fluency, an ability which Goodman and trumpeter Harry James both possessed.

As an improviser, Harris seemed comfortable playing among divergent stylists, as shown on Jazz at the Philharmonic recordings, as his "one-off" style seemed to work in any context, from Dixieland, to swing, or bebop.

Later, Harris worked in Las Vegas, Nevada, finally retiring to Florida.
