Moerschieder Borr, nature reserve in Mörschied, Rhineland-Palatinate, Germany

Moerschieder Borr is a protected nature reserve in the town of Mörschied, Germany, covering about 20 hectares of dense forest with rocky slopes and quartzite stone formations. Walking trails wind through the area, with some paths following the edges of rocky outcroppings and leading to a summit at nearly 650 meters (2,130 feet) above sea level.

The Mörschieder Borr was designated a nature reserve in 1940 and covers about 19.7 hectares under reserve number 7134-076. Since the Hunsrück-Hochwald National Park was created in 2015, the reserve has lain in its nature zone 1b, an development zone, in the park's northeastern corner.

The reserve lies southwest of Mörschied's centre, in the triangle formed by Mörschied, Kempfeld and Herborn; the Saar-Hunsrück-Steig climbs to the 646 m summit. The area is 1.12 km long and at most about 270 m wide, so the marked paths along the boundary and to the top are short walks. The southeast slope holds open quartzite scree where footing is loose.

The summit of the Mörschieder Burr is made of Taunus quartzite, and the southeast slope below it holds largely vegetation-free scree of quartzite rock. The Saar-Hunsrück-Steig long-distance trail runs up to the 646 m top, which lies just under 2 km northeast of the Wildenburger Kopf with its ruin.
