The Diocese of Spiš (Slovak: Spišská diecéza, Latin: Dioecesis Scepusiensis, Hungarian: Szepesi egyházmegye) is a Latin Church diocese of the Catholic Church in northern Slovakia.

Its seat is in Spišská Kapitula; the diocese covers an area of 7,802 km2 with 583,633 people of which 76.6% are of Catholic faith (2004).

The seat was vacant for three years after the death of bishop Štefan Sečka.

[4] The diocese was established in the Kingdom of Hungary on 13 March 1776 as a suffragan of the Archdiocese of Esztergom.

On 30 December 1977, it was taken from the former and became part of the newly created Slovak ecclesiastical province with metropolitan being the Diocese of Trnava.
