Yes, Anchorage, Alaska is entirely above sea level. The city sits on the upper Cook Inlet, an arm of the Gulf of Alaska, with elevations ranging from approximately 20 to 1,200 feet (6 to 366 meters) above sea level across its municipal area.
Anchorage occupies a glaciated coastal lowland backed by the Chugach Mountains. The gradual rise from inlet to foothills creates distinct microclimates—cooler, snowier, and windier on the Hillside. The city's elevation protects it from sea-level rise concerns affecting many coastal cities, though glacial isostatic adjustment (land rising as ice mass diminishes) is a measurable phenomenon.
The elevation range contributes to Anchorage's unique blend of maritime influence (moderated temperatures, heavy snow) and alpine access (Chugach State Park begins at city limits).
