Monsignor Dilwyn Lewis (28 April 1924 – 10 July 2000) was a British clothes designer turned Roman Catholic priest who oversaw the restoration of the ancient Basilica di Santa Maria Maggiore in Rome.
Raised in an orphanage, Bridgend Cottage Homes, in his birth town of Bridgend in Wales, Dilwyn John David Lewis studied for the ministry in the Church of England at Kelham College but instead became a clothing salesman before embarking on a successful career as a freelance clothing designer in London.
In addition to assisting with restoration, Lewis organised musical performances and special events at the Basilica and coordinated collaborations with the Church of England, including arranging for the loan of St. Thomas Becket's yellow silk dalmatic to the Canterbury Cathedral and for the celebration in the Basilica of the Eucharist by Anglican priests.
Dilwyn Lewis was buried in the crypt of Basilica di Santa Maria Maggiore following his death in Ireland in 2000.
