Orpheus Gate (Orfeeva Porta \or-'fe-e-va 'por-ta\), also Orpheus Pass, is the 548 m high and 380 m wide pass in eastern Livingston Island in the South Shetland Islands, Antarctica, bounded by Pliska Ridge on the southeast and Polanco Peak in Burdick Ridge on the northwest, Huntress Glacier on the southwest and Perunika Glacier on the northeast.

The pass forms part of the overland routes from Hurd Peninsula via Willan Saddle, the southern foothills of Burdick South Peak, and Orpheus Gate to upper Perunika Glacier, Wörner Gap and Camp Academia area, upper Huron Glacier, Tangra Mountains and Bowles Ridge.

Orpheus, a name of world and national culture, was originally applied in 1995 to a nearby peak but, due to the priority of the existing British nameform Willan Nunatak, was subsequently transferred to the present feature.
