Pandemonium is an 1841 oil painting by the English artist John Martin. It combines landscape painting with literature, depicting a scene featuring Pandæmonium inspired by the 1667 poem Paradise Lost by John Milton. Reflecting the Romantic style of the era, Martin also produced engravings featuring a similar scene. It was displayed at the Royal Academy Exhibition of 1841 at the National Gallery in London. The painting is now in the collection of the Louvre in Paris, which acquired it in 2006.
