The Letters of Vincent van Gogh is a collection of 903 surviving letters written (820) or received (83) by Vincent van Gogh. More than 650 of these were from Vincent to his brother Theo. The collection also includes letters van Gogh wrote to his sister Wil and other relatives, as well as between artists such as Paul Gauguin, Anthon van Rappard, and Émile Bernard.
Johanna van Gogh-Bonger, the wife of Vincent's brother Theo, spent many years after her husband's death in 1891 compiling the letters, which were first published in 1914. Arnold Pomerans, editor of a 1966 selection of the letters, wrote that Theo "was the kind of man who saved even the smallest scrap of paper", and it is to this trait that the public owes the 663 letters from Vincent.
