Neny Fjord (68°16′S 66°50′W / 68.267°S 66.833°W / -68.267; -66.833 (Neny Fjord)) is a bay, 10 nautical miles (19 km; 12 mi) long in an east–west direction and 5 nautical miles (9.3 km; 5.8 mi) wide, between Red Rock Ridge and Roman Four Promontory on the west coast of Graham Land, Antarctica.

[1] Neny Fjord is in the east of the larger Marguerite Bay in Graham Land on the Fallières Coast of the Antarctic Peninsula.

[2] This coast was first explored in 1909 by Dr. Jean-Baptiste Charcot who, it appears, gave this name to a feature somewhat north of the bay described.

The British Graham Land Expedition (BGLE) made a detailed survey of this area in 1936–1937, and in correlating their work with that of Charcot applied the name Neny Fjord to the bay between Red Rock Ridge and Roman Four Promontory.

A glacier, 8 nautical miles (15 km; 9.2 mi) long, which flows from the north slopes of Mount Lupa northwestward along the northeast side of the Blackwall Mountains into Providence Cove, Neny Fjord.

This feature together with Gibbs Glacier, which flows southeast, occupy a transverse depression between Neny Fjord and Mercator Ice Piedmont on the east side of the Antarctic Peninsula.

Small steep glacier flowing northwest to Neny Bay between Mount Nemesis and Roman Four Promontory.

Cove bounded by ice cliffs which lies at the foot of Remus Glacier in the southeast corner of Neny Fjord.

It was resurveyed in 1940-41 by members of the USAS, and so named by them because on first arrival it seemed providential that a site for the East Base was found so quickly and easily.

The west side of this mountain was first roughly surveyed in 1936 by the British Graham Land expedition (BGLE) under John Rymill.

The feature was photographed from the air and ground by the Ronne Antarctic Research Expedition (RARE), 1947–48, under Ronne, who named it for Harold M. Dudley, executive secretary of the American Council of Commercial Laboratories, Inc., Washington, DC, who procured various types of equipment and arranged financial aid for RARE.
