The Eisbach, locally known as die Eis, is a 38-kilometre (24 mi) long river and left or western tributary of the Rhine in the northeastern Palatinate and southeastern Rhenish Hesse, in the German state of Rhineland-Palatinate.

The largest of the seven springs of the Eisbach is at an elevation of about 290 metres (950 ft) above sea level on the northern slope of the Hohe Bühl mountain, 443 metres (1,453 ft), in the northern Palatinate Forest, southwest of Ramsen. After about two kilometres, the seven streams unite in the Eiswoog reservoir. At the hamlet of Kleehof, the 3.5-kilometre (2.2 mi) long Bockbach flows in from the right. Here, the direction of the river changes from straight north to northeast. The direction remains northeast until the confluence with the Rhine.

The river then flows past Ramsen and Eisenberg. Below Ebertsheim, it receives the 5-kilometre (3.1 mi) long Seltenbach from the right and a few metres further, its largest tributary, the Rodenbach from the left. At Asselheim, a ward of Grünstadt, the Eisbach reaches the Upper Rhine Valley. It then flows through the wards of Albsheim, Mühlheim and Colgenstein, then Obrigheim itself and finally the hamlet of Neuoffstein. Here, it receives up to 350 cubic metres (12,000 cu ft) per work day of waste water from the sugar beet processing plant Südzucker-Werk Offstein.

At Offstein, it crosses the border into Rhenish Hesse. It then flows past some southwestern and southern wards of Worms, viz. Heppenheim, Horchheim and Weinsheim. Near State Road 523, the Mariamünsterbach branches off. During the middle ages, this stream provided the tanning and dyeing industries in Worms with water; in the 19th century it was covered. From this point onwards, the Eisbach is called Altbach ("old brook") and flows south of the Worms city centre, through the Bürgerweide ward. It flows into the Upper Rhine at the southern tip of the Worms marina, at an elevation of 89 metres (292 ft).
