Judah and Tamar is an 1840 oil painting by the French artist Horace Vernet.

It portrays a biblical scene featuring the windowed Tamar who seduces her father-in-law Judah while disguised as a prostitute.

[1] Vernet was inspired by his trips to recently conquered Algeria to paint biblical scenes featuring Arabs.

[2] Vernet exhibited the work at the Salon of 1843 at the Louvre in Paris.

Today it is in the Wallace Collection in London, having been acquired by Marquess of Hertford in 1865.
