Ushlinova Peak (Bulgarian: връх Ушлинова, ‘Vrah Ushlinova’ \'vr&h ush-'li-no-va\) is the sharp ice-covered peak of elevation 2150 m in the west foothills of Avery Plateau on Loubet Coast in Graham Land, Antarctica. It surmounts Widdowson Glacier to the west and a tributary to that glacier to the northeast.
The peak is named after Donka Ushlinova (1880-1937), a participant in the Bulgarian liberation movement in Macedonia, much decorated for her bravery in the 1912-1918 wars of national unification.
