Sailboats and Estuary (also The Entrance to the Port of Roscoff, French: L'entrée du port de Roscoff) is an oil on canvas painting by Belgian painter Théo van Rysselberghe. Painted around 1887, it shows a coastal landscape elaborated in a Pointillist technique. Van Rysselberghe probably adopted the Pointillist manner after befriending Signac; however, the use of color in Sailboats and Esuary is nonetheless far more realistic than in paintings by Signac and other Neo-Impressionists, and reveals a tendency towards naturalism. The artwork has been in the collection of the Musée d'Orsay in Paris since 1982, on loan from the Louvre.
