Modern Rome – Campo Vaccino is a landscape by British artist Joseph Mallord William Turner completed in 1839. It is Turner's final painting of Rome and had been in the possession of the family of the 5th Earl of Rosebery since 1878, until the painting came to auction, 7 July 2010. It was bought by the J. Paul Getty Museum, Los Angeles, and was subject to an export bar to allow a British gallery time to attempt to match the Getty's bid.

Joseph Mallord William Turner, known in his time as William Turner, was an English Romantic painter, printmaker and watercolourist. He is known for his expressive colouring, imaginative landscapes and turbulent, often violent marine paintings. He left behind more than 550 oil paintings, 2,000 watercolours, and 30,000 works on paper. He was championed by the leading English art critic John Ruskin from 1840, and is today regarded as having elevated landscape painting to an eminence rivalling history painting.
