Despot or despotes () was a senior Byzantine court title that was bestowed on the sons or sons-in-law of reigning emperors, and initially denoted the heir-apparent of the Byzantine emperor. From Byzantium it spread throughout the late medieval Balkans and was also granted in the states under Byzantine cultural influence, such as the Latin Empire, the Second Bulgarian Empire, the Serbian Empire and its successor states (Bulgarian and ), and the Empire of Trebizond. With the political fragmentation of the period, the term gave rise to several principalities termed "despotates" which were ruled either as independent states or as appanages by princes bearing the title of despot; most notably the Despotate of Epirus, the Despotate of the Morea, the Despotate of Dobruja and the Serbian Despotate. In modern usage, the word has taken a different meaning: "despotism" is a form of government in which a single entity rules with absolute power. The semantic shift undergone by the term is mirrored by "tyrant", an ancient Greek word that originally bore no negative connotation, and the Latin "dictator", a constitutionally sanctioned office of the Roman Republic. In colloquial Modern Greek, the word is often used to refer to a bishop. In English, the feminine form of the title is despotess (from ; ; /), which denoted the spouse of a despot, but the transliterated traditional female equivalent of , (), is also commonly used.

Occasionally it was used in formal settings, for example on coins (since Leo III the Isaurian) or formal documents. During the 8th and 9th centuries, co-emperors appear on coinage with the address , but this was still a mark of respect rather than an official title. Senior emperors were also occasionally addressed as . Before the 12th century, the honorific was used interchangeably with the more formal title of basileus. Although it was used for high-ranking nobles from the early 12th century, the title of despot began being used as a specific court title by Manuel I Komnenos, who conferred
