Daniel Rock (31 August 1799, Liverpool – 28 November 1871 Kensington, London) was an English Roman Catholic priest, ecclesiologist and antiquarian.
On his return to London he became assistant priest at St. Mary's, Moorfields, until 1827, when he was appointed domestic chaplain to John Talbot, 16th Earl of Shrewsbury, with whom he had contracted a friendship based on similarity of tastes while at Rome.
He accordingly resided at Alton Towers, Staffordshire, till 1840, with the exception of two years during which Shrewsbury's generosity enabled him to stay at Rome collecting materials for his great work, Hierurgia or the Holy Sacrifice of the Mass, which was published in 1833.
In 1840 he became chaplain to Sir Robert Throckmorton of Buckland (then in Berkshire, nowadays in Oxfordshire), and while there wrote his greatest book, The Church of Our Fathers,[1] in which he studies the Sarum Rite and other medieval liturgical observances.
Shortly after, he ceased parochial work, and having resided successfully at Newick, Surrey (1854–64), he went to live near the South Kensington Museum in which he took the keenest interest and to which he proved of much service.
