Lasta (Ge'ez: ላስታ lāstā) is a historic district in north-central Ethiopia. It is the district in which Lalibela is situated, the former capital of Ethiopia during the Zagwe dynasty and home to 11 medieval rock-hewn churches.
According to G.W.B. Huntingford, Lasta is first mentioned in the fourteenth century, although it obviously had been inhabited long before that. In the 18th century the Czech Franciscan Remedius Prutky listed Lasta as one of the 22 provinces of Ethiopia still subject to the Emperor, but singled Lasta out as one of the six he considered "large and truly deserving of the name of kingdom." Its neighbor to the west was Begemder and to the north Wag.
