Backlund is a worn lunar impact crater on the far side of the Moon, beyond the eastern limb, astride the southern rim of the walled plain Pasteur, to the west of the crater Hilbert. Further to the west-southwest is Sklodowska. Backlund's north and south ends are more worn and eroded than the intervening stretches. The interior floor is relatively flat, with the usual accompaniment of tiny impact craters marking the surface.

The name "Backlund" honours the Swedish-born Russian astronomer Oskar Andreevich Baklund (Russian: Оскар Андреевич Баклунд, 1846-1916).
