The Military Ordinariate of Slovakia () is a Latin military ordinariate of the Roman Catholic Church for the Slovak armed forces.
It is exempt and immediately subject to the Holy See(not part of any ecclesiastical province and its Roman Congregation for Bishops).
The episcopal see is Saint Sebastian's Cathedral (Katedrála sv. à  ebastiána) in the Slovak capital of Bratislava. Prior to 2009, the seat was the Trinitarian Church in the same city, formally the Cathedral of St. John of Matha and St. Felix of Valois (Katedrála sv. Jána a sv. Felixa z Valois).
The military ordinariate, without precursor, was established by Pope John Paul II on 20 January 2003, ten years after the country's independence by the dissolution of Czechoslovakia.
As per 2014, it provides pastoral care to Roman Catholics serving in the Slovak Armed Forces and their families in 56 parishes with 54 priests (46 diocesan, 8 religious), 1 deacon and 8 lay religious brothers.
