Yankov Gap (Yankova Sedlovina \'yan-ko-va se-dlo-vi-'na\) is an ice-covered saddle linking Melnik Ridge and Bowles Ridge in eastern Livingston Island in the South Shetland Islands, Antarctica. The gap is at an elevation of 575 m and extends 1 km in the north-south direction from Samokov Knoll in Melnik Ridge to Asparuh Peak in Bowles Ridge. Yankov Gap is part of the divide between the glacial catchments of the head of Kaliakra Glacier to the west and Struma Glacier to the east.

The gap was first crossed by the Bulgarians Lyubomir Ivanov and Doychin Vasilev from Camp Academia on 28 December 2004. Named after Yordan Yankov, a radio-engineer at St. Kliment Ohridski Base in several seasons since 1995.

The gap's midpoint is located at 62°36′28″S 60°09′48″W / 62.60778°S 60.16333°W / -62.60778; -60.16333, which is 1.99 km northwest of Pirdop Gate, 1.78 km east-northeast of Omurtag Pass and 4.76 km southeast of Elhovo Gap (Mapped in 2005 and 2009 from the Bulgarian topographic survey Tangra 2004/05).
