'''Rongel Reef''' ({{langx|bg|Rif Rongel}} 'rif ron-'zhel), is a moraine reef in the Emona Anchorage in the eastern parts of Livingston Island in the South Shetland Islands, Antarctica. The reef emerged during a glacier retreat in the late 20th and early 21st centuries.

The reef extends over {{convert|600|m|yd|0|abbr=on}} in northeast–southwest direction and is partly exposed at low tide and submerged at high tide but for the islet rising to near {{convert|3|m|ft|1|abbr=on}} at its northeast extremity.

Its midpoint is located {{convert|2.85|km|mi|abbr=on}} north-northwest of Hespérides Point, {{convert|3.12|km|mi|abbr=on}} west of Aleko Point, and {{convert|3.35|km|mi|abbr=on}} northeast by east of Ereby Point. The northeast extremity of Rongel Reef is located {{Convert|75|m|yd|0|abbr=on}} south-southwest of Rongel Point. A {{convert|710|m|yd|0|abbr=on}} wide nameless cove is indenting for {{convert|250|m|yd|0|abbr=on}} the coast behind Rongel Reef, the northeast side of its entrance formed by Rongel Point. The southwest extremity of Rongel Reef is located {{convert|300|m|yd|0|abbr=on}} southeast of the nameless point located {{convert|3.18|km|mi|abbr=on}} northwest by north of Hespérides Point and {{convert|3.04|km|mi|abbr=on}} northeast by east of Ereby Point.

The feature is named after the Brazilian Navy ship ''Ary Rongel'', in recognition of her logistic support for the Bulgarian Antarctic programme.

==Location== The reef is centered at {{coord|62|37|16|S|60|24|11|W}} (Bulgarian mapping from a topographic survey of the region made from 8 December 1995 to 8 February 1996).
