Avren Rocks (Bulgarian: Скали Аврен, romanized: Skali Avren ska-'li a-'vren) are three adjacent rocks situated in the interior of Micalvi Cove in the south extremity of Robert Island, South Shetland Islands.

The rocks were first mapped in 2008 by a Bulgarian team.

They are named after two settlements in Varna and Kardzhali provinces situated in northeastern and southeastern Bulgaria respectively.
