Vilikaila or Viligaila was one of the 5 elder Lithuanian dukes mentioned in the peace treaty with Halych-Volhynia in 1219. He is mentioned as brother of Daujotas, which leads to believe he was the younger or perhaps less influential brother. He is not mentioned in any other sources. Tomas Baranauskas, a modern Lithuanian historian, believes that Vilikaila and Daujotas might be sons of Stekšys, a Lithuanian duke killed in 1214.
