Nesebar Gap (Sedlovina Nesebar \se-dlo-vi-'na ne-'se-b&r\) is a 1.3 km wide gap in eastern Livingston Island in the South Shetland Islands, Antarctica bounded to the west by Pliska Ridge and to the east by the northern slope of Mount Friesland, Tangra Mountains. It is part of the divide between the glacial catchments of Perunika Glacier to the north and Huntress Glacier to the south. The gap is part of an overland route between Orpheus Gate to the west, and Camp Academia locality and Lozen Saddle to the east.

The Nesebar Gap was first mapped in detail by the Spanish Servicio Geográfico del Ejército in 1991. Nesebar is the name of a town on the Bulgarian Black Sea Coast.

The gap is located at 62°38′43″S 60°12′16″W / 62.64528°S 60.20444°W / -62.64528; -60.20444 (Elevation 550 m).
