Thoughts of the Past is an oil painting on canvas by English Pre-Raphaelite artist John Roddam Spencer Stanhope, first exhibited in 1859 and currently housed at Tate Britain.

Known as one of the "second-generation" of Pre-Raphaelites, Stanhope was among Dante Gabriel Rossetti's mural-painting party at the Oxford Union in 1857, together with Arthur Hughes, John Hungerford Pollen, Valentine Prinsep, Ned Burne-Jones and William Morris (nicknamed Topsy).

Works such as Thoughts of the Past and Rossetti's Found (1855) allowed the genteel gallery-going public to sympathise with societal problems - from a safe distance.

It was pictures such as William Holman Hunt's The Awakening Conscience (1854), illustrating a married man and his mistress, which were regarded as threatening to Victorian family life.
