沃尔夫冈·克特勒（Wolfgang Ketterle，1957年10月21日－）是一位德国物理学家，现任麻省理工学院物理学教授。他的研究专注在冷原子的捕捉，以使这些原子接近绝对零度。在1995年时，他所领导的团队，成为首先获得玻色-爱因斯坦凝聚的团队之一。由于这些研究，使他与埃里克·康奈尔以及卡尔·威曼，因「在碱金属原子稀释气体中（制成）玻色-爱因斯坦凝聚的成就，以及关于凝聚特性的早期基础研究」，共同获颁2001年诺贝尔物理学奖，三人平分奖金。

Wolfgang Ketterle (born 21 October 1957) is a German physicist and professor of physics at the Massachusetts Institute of Technology (MIT). His research has focused on experiments that trap and cool atoms to temperatures close to absolute zero, and he led one of the first groups to realize Bose–Einstein condensation in these systems in 1995. For this achievement, as well as early fundamental studies of condensates, he was awarded the Nobel Prize in Physics in 2001, together with Eric Allin Cornell and Carl Wieman.
