Henry Patrick Clarke RHA (17 March 1889 – 6 January 1931) was an Irish stained-glass artist and book illustrator.

[citation needed] Clarke was educated at the Model School in Marlborough Street, Dublin and Belvedere College, which he left in 1905.

[2][3] Clarke was then apprenticed into his father's studio and attended evening classes in the Metropolitan College of Art and Design.

[4] At the art school in Dublin, Clarke met fellow artist and teacher, Margaret Crilley.

Picked up by London publisher Harrap,[3] he started with two commissions which were never completed: Samuel Taylor Coleridge's The Rime of the Ancient Mariner (much of his work on which was destroyed during the 1916 Easter Rising in Dublin) and an illustrated edition of Alexander Pope's The Rape of the Lock.

It was followed by editions of The Years at the Spring, with 12 colour plates and more than 14 monotone images; (Lettice D'Oyly Walters, ed., 1920), Charles Perrault's Fairy Tales of Perrault, and Goethe's Faust, with eight colour plates and more than 70 halftone and duotone images (New York: Hartsdale House, 1925).

[5] Two of his most sought-after titles are promotional booklets for Jameson Irish Whiskey: A History of a Great House (1924, and subsequent reprints) and Elixir of Life (1925), which was written by Geofrey Warren.

A headstone was erected, but local law required that the family pledge to maintain the grave 15 years after the death.
