Christen Mikkelsen Kold (sometimes spelled Kristen or Cristen; 29 March 1816 — 6 April 1870) was a Danish teacher, notable for creating the Danish Folk high school system, for non-degree education of adults. Kold was born in Thisted, Jutland. Unsatisfied with the education system of Denmark at the time, he founded a school in Ryslinge in 1851, which later became a model for the folk high-school system. His work has to be seen in context with that of N. F. S. Grundtvig. He associated with Morten Eskesen. Kold died in Dalum, Funen.
