The Rotter Nemere or just Nemere was a Hungarian high performance, single seat sailplane designed and built for the 1936 ISTUS gliding demonstration held in 1936 alongside the Berlin Olympic Games.

The ISTUS international soaring demonstration was held at the same time and in the same place as the 1936 Olympics to make the case for gliding's inclusion as an Olympic discipline at later Games. The proposition was accepted and there would have been gliding events at the 1940 Olympics had not World War II intervened. Rotter, using his experience of designing the successful Karakán, was responsible for both designing and flying the Nemere, Hungary's representative.

The Nemere's progression from the Karakán was most evident in the wing and its mounting. The modified pedestal mounting to the fuselage had gone and instead the Nemere had a shoulder wing mounted on a 1,150 mm (45.3 in) span centre section built as part of the fuselage. The wing was a cantilever structure, without the earlier lift struts, continuously tapered in plan from root to tip with no externally distinct centre section and with 2° of dihedral. There was continuous taper in wing section also; Rotter returned to Göttingen airfoils using Gö 646 with a thickness to chord of 19% at the root, varying through Gö 535 to a thinner, less cambered, tip. Like the Karakán, the Nemere had a plywood covered D-box ahead of the main spar but, with the external struts absent, plywood covered more of the inner wing back to a diagonal internal drag strut. The wings were fabric covered aft. Broad chord ailerons occupied the outer 60% of the wings, which ended in elliptical tips.
