Keast is an English surname of Cornish origin. Its earliest known use is recorded in the English county of Cornwall, a region in the South West of England that has historically maintained a distinct linguistic and cultural heritage. The name is broadly associated with the Christian population of the British Isles, and the surname has been borne by individuals of Anglo‑Saxon descent for several centuries.

The etymology of Keast is typically regarded as topographical or locational, deriving from the Old English word cest, which means a “wooded hill.” The surname identified a person who lived near or upon such a hill, a common practice in medieval England for distinguishing individuals who shared a given name. Alternative theories propose a derivation from the Old English east, meaning “eastern enclosure or homestead,” or from the Cornish Coes (wood), indicating a dwelling within or near a forested area. The latter accounts for the occasional use of spelling variants such as Keeste and Keist.

Historical records place the earliest mention of the surname around the year of the Spanish Armada, 1588, with a marriage entry for Blanch Keast in Landrake, Cornwall. Subsequent documents, including the Kent Rolls of 1292, document individuals bearing the name in other counties, yet these instances remain uncommon and are often considered secondary references. The spelling of the name evolved over time, moving from forms such as Kate or Kette to the modern orthography Keast, as reflected in contemporary parish registers.

In contemporary times, the distribution of Keast remains heavily centred on Cornwall and Devon, with Scottish or English populations also including the surname in relatively small numbers. The name has travelled beyond the British Isles through emigration in the 18th and 19th centuries, and it is now found in limited frequencies in countries such as Australia, New Zealand, Canada and the United States. Despite this spread, the surname is still comparatively rare worldwide, ranking low on common surname lists in those overseas nations.

Variations of the surname include Keist, Kest, Keeste, keyst and Kyste. Although these forms appear similar, many researchers regard them as distinct surnames with separate etymological pathways; nevertheless, they are occasionally conflated in informal records. Modern genealogical resources may provide further details on the lineage of individuals who carry the Keast name, enabling precise tracing of ancestral ties to the South West of England.
