The Nandi Resistance was a military conflict that took place in present-day Kenya between 1890 and 1906. It involved members of the Kalenjin ethnic group, mainly from the Nandi section, and the British colonial administration. The close of the 19th century, a time referred to as the "pacification period" by Matson, saw a number of local populations that resisted British colonial rule. Of these, the Nandi resistance would stand out for being the longest and most tenacious.

The Nandi are part of the Kalenjin, a Nilotic tribe living in East Africa. The Nandi ethnic group live with close association and relation with the Kipsigis tribe. They traditionally have lived and still form the majority in the highland areas of the former Rift Valley Province of Kenya, in what is today Nandi County. They speak the Nandi dialect of the Kalenjin language.
