Tarring a Boat (French - Le Bateau goudronné) is an 1873 oil-on-canvas painting by Édouard Manet, painted at Berck beach during one of his regular summer stays in Boulogne-sur-Mer. It shows the hull of a fishing boat being tarred. In it he used a darker palette than usual, typical of his work of that period. It is now in the Barnes Foundation in Philadelphia.
