The Portrait of Adam Mickiewicz on the Ayu-Dag Cliff (Polish: Portret Adama Mickiewicza na Judahu skale) is an oil portrait of Adam Mickiewicz by Walenty Wańkowicz created from 1827 to 1828.

Since 1925 it has been in the collection of the Warsaw National Museum.

[1] Created in the Romanticism style,[1][2] the portrait depicts Mickiewicz in a Byronic pose leaning on a cliff of the Ayu-Dag Mountain, Crimea overseeing the Black Sea, coated in a burka (a coat of the highlanders of Caucasus).

The theme and the title of the portrait come from the first line of the last sonnet Ajudah (translated as "On Juda's Cliff") of The Crimean Sonnets by the poet: Wańkowicz befriended Mickiewicz at the Vilnius University.

At that time Mickiewicz introduced Wańkowicz to Alexander Pushkin, and Wańkowicz started to work on the portrait of Pushkin as a pair to that of Mickiewicz.
