Baronius Press is a Catholic book publisher based in London, England. It was originally founded in 2002 and takes its name from the Venerable Cardinal Caesar Baronius, a Neapolitan ecclesiastical historian from the late 1500's. Its logo is a biretta, which together with a cassock forms the traditional image of a Catholic priest.

Baronius Press as a Roman Catholic company, is completely loyal to the Pope and Magisterium, and is committed to producing good solid Catholic books and resources that reaffirm the faith and the tradition of the Church. Whilst the main office is based in London, thanks to electronic communications, we work with individuals and organisations in America, Australia and Europe to produce our titles.
