Hartsop Dodd is a fell in the English Lake District, standing to the south east of Brothers Water.

A broad grassy ridge descends gently from Caudale Moor, running north from the summit plateau and topped by a stone wall.

After this the ridge drops quickly to valley level between Hartsop village and Brothers Water.

The western flank of the ridge stands above the high valley of Caudale, which is a feeder of Kirkstone Beck and Brothers Water.

At the point where the ridge narrows and turns, a short spur is thrown out on the eastern side.
