Portrait of Mirza Abul Hasan is an 1810 portrait painting by the English artist Thomas Lawrence depicting Mirza Abolhassan Khan Ilchi, the Persian envoy to Britain.

The painting was commissioned by Sir Gore Ouseley who had been appointed as the ambassador's guide during his stay on Britain.

Lawrence, a future President of the Royal Academy, was a leading portraitist when he received the commission.

Lawrence was unused to painting beards, as the Regency era fashion was for clean-shaven faces.
