Gyldén is the remnant of a lunar crater that is located to the northeast of the Ptolemaeus walled plain on the moon. It lies along the prime meridian of the selenographic coordinate system, and less than 150 km south of the lunar equator. Nearby craters of note include Herschel to the west, the flooded Réaumur to the north, and the Hipparchus walled plain to the east.

The heart-shaped rim of this crater is in poor condition, having been eroded by impacts until the disintegrating remnants form an uneven ring of peaks and valleys around the interior floor. The satellite crater 'Réaumur A' is attached to the northern rim. A wide cleft cuts through the western rim, continuing to the north-northwest past Spörer crater. The interior floor is relatively featureless, although the small crater 'Gyldén K' is located just to the southeast of the mid-point.

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 Gyldén crater.
