The Baybay language, also known as Baybayanon, Utudnon, Waya-Waya or Leyte, is a distinct regional language that was spoken on the island of Leyte in the Philippines before the arrival of Waray and then later, Boholano and Cebuano.

Baybayanon was originally a Warayan language that has been relexified and overlaid by a Cebuano (Leyteño) superstratum.

[2] The Warayan substratum is characterized by Baybayanon's more Waray-like deictics, and various other features.

[2] Utudnon is spoken by about 10,000 people in five barangays of Baybay municipality,[3] central Leyte, namely Utúd (also called Utod or Guadalupe), Gábas, Kilím, Pátag, Pangasúgan and Hibunawan.
