The Treachery of Images (French: La trahison des images, 1928–29, sometimes translated as The Treason of Images) is a painting by the Belgian René Magritte, painted when Magritte was 30 years old. The picture shows a pipe. Below it, Magritte painted, "Ceci n'est pas une pipe.", French for "This is not a pipe."

The famous pipe. How people reproached me for it! And yet, could you stuff my pipe? No, it's just a representation, is it not? So if I had written on my picture "This is a pipe," I'd have been lying![2]

The theme of pipes with the text "Ceci n'est pas une pipe" is extended in his 1966 painting, Les Deux Mystères.[3] Currently it is shown at the Los Angeles County Museum of Art.
