Plivain, also known as Plivano or Pleban, was the lord of Botrun (now Batroun in Lebanon) in the County of Tripoli from around 1180 to around 1206. He was a merchant from Pisa who settled in the county in the late 1170s. He seized Botrun through his marriage to its heiress, Lucia. According to a late source, he bribed Lucia's suzerain, Count Raymond III of Tripoli, into allowing the marriage. He fell into captivity in the Battle of Hattin on 4 July 1187.
