Jeypore Estate or Jeypore Zamindari was a Zamindari estate of the Madras Presidency in British India. Historically it was a kingdom known as Jeypore Kingdom, located in the highlands of the western interiors of the Kalinga region that existed from the mid-15th century to 1777 CE as a tributary state of the Gajapati Empire and following its decline retained various degrees of semi-independence until it became a vassal state of the British. It eventually formed a part of the linguistic Orissa Province in 1936 upon transfer from the Madras Province and became a part of the independent Union of India in 1947.
