Wayne Lamar Jackson (November 24, 1941 – June 21, 2016) was an American soul and R&B musician, playing the trumpet in The Mar-Keys, in the house band at Stax Records and later as one of The Memphis Horns, described as "arguably the greatest soul horn section ever".

Jackson was also the voice on the Mar-Keys singular hit "Last Night", due in part, to his proximity to the microphone
