Alexander de Kylwos (died 1398) – written alternatively as Frylquhous, Kylquos, and a variety of other forms – was a Scottish churchman and prelate active in the second half of the 14th century. He is known to have held senior positions in three bishoprics, and senior offices in two, before being elected and appointed Bishop of Ross in 1371. Though his episcopate is relatively obscure, he seems to have spent almost all of it inside or around his province, was closely associated with William III and Euphemia I, successive rulers of Ross, and was an associate of the famous Alexander Bur, Bishop of Moray, during the latter's struggle with Alexander Stewart, the son of the King later known by the nickname "Wolf of Badenoch".
