Rue Saint-Honoré, dans l'après-midi. Effet de pluie

Rue Saint-Honoré, dans l'après-midi. Effet de pluie is an 1897 oil painting by Camille Pissarro. The work was made towards the end of Pissarro's career, when he abandoned his experiments with Pointillism and returned to a looser Impressionist style.

It is part of a series of works that Pissarro made in 1897-98 from a window of the Hôtel du Louvre, looking down across the edge of the place du Théâtre Français and along the rue Saint-Honoré, portraying the people, carriages and buildings, the trees, fountains and streetlamps, in an early afternoon shower of rain. Other paintings in the series depict a similar scene in morning sunlight, or in the shadows of the evening. The painting measures 81 cm × 65 cm.

The painting has been displayed at the Museo Thyssen-Bornemisza in Madrid since the museum opened in 1992. It had been bought by Baron Hans Heinrich Thyssen-Bornemisza at the Hahn Gallery in New York in 1976, from a US collector who bought it at the Knoedler Gallery in New York in 1952. In 1993, the baron sold it with the rest of his collection of 775 works to the Spanish state for US$350 million.

A claim that the painting was Nazi looted art was dismissed by US federal courts in 2019 and 2020, on the grounds that the law of Spain applied. However, in September 2021, the U.S. Supreme Court accepted certiorari to review that decision, and on 21 April 2022, the Court ruled that the lower courts had incorrectly applied federal common law to apply Spanish law when they should have applied the law of California, and remanded the case for further proceedings.

On January 9, 2024, the federal intermediate appellate court ruled in favor of the Museo Thyssen-Bornemisza by holding that California would apply its law on conflict of laws in such a way as to defer to the law of Spain.
