Killing a Deer or A Deer Hunt – The Kill (French: L'Hallali du cerf), is a very large painting (355 by 505 cm) representing a hunting scene, completed in 1867 by the French Realist painter Gustave Courbet.

It is in the large format newly adopted by Courbet, as also in A Burial at Ornans and The Artist's Studio.

The picture caused some scandal, major formats being previously reserved for noble history paintings rather than hunting scenes.

The scene shows a deer attacked by a pack of hunting dogs, collapsed on the snowy ground.

The drill is Cusenier Jules, a resident of Ornans while the man on horseback is Felix Gaudy, of Vuillafans.
