Hagecius is a lunar impact crater in the southeastern part of the Moon's near side. This crater forms a triangular formation with Rosenberger crater to the north-northwest, and Nearch crater to the west-northwest. Like both of these craters, Hagecius has undergone erosion from subsequent impacts, and its outer rim is worn and irregular. The southeastern rim in particular is overlaid by three smaller craters designated 'Hagecius C', 'B', and 'G'.

The interior floor of Hagecius is a level plain with no significant rises. There is a small craterlet to the northwest of the mid-point, and a few tiny craterlets marking the southeastern half of the floor. About a third of the interior floor on this side is also overlaid by the outer ramparts of the three satellite craters mentioned above.

To the northeast of Hagecius is Biela crater, a younger formation with more distinctive features.

[edit] Satellite craters

By convention these features are identified on lunar maps by placing the letter on the side of the crater mid-point that is closest to Hagecius crater.
