Norman Percy Grubb MC (2 August 1895 - 15 December 1993) was a notable British Christian missionary, writer, and theological teacher. As a student at Cambridge, he was one of the founders of what ultimately became InterVarsity Christian Fellowship. His early work as a missionary was in the Congo with C. T. Studd, whom he followed as the Director of what is now WEC International.
A highly sought-after speaker, Norman Grubb was often chosen as a devotional speaker at Presidential Prayer Breakfasts. He carried on this work until his death in 1993, having lived 98 years.
