Blessed Teofilius Matulionis (22 June 1873 – 20 August 1962) was a Lithuanian prelate of the Roman Catholic Church.
He was consecrated a bishop in secret and spent most of his years as bishop in prison.
His death was likely due to poisoning by officials of the USSR.
Pope Francis approved his beatification on 1 December 2016 and it was celebrated in Vilnius at the cathedral square on 25 June 2017.
