Easternmost U.S. State: Maine

Maine is the **easternmost state** in the United States.

Key geographic points:

• West Quoddy Head (Lubec): Easternmost point of **contiguous U.S.** (66°57'W).
• Sail Rock (off West Quoddy): Easternmost land (rock) of U.S.
• Semisopochnoi Island, Alaska (179°46'E): Technically **easternmost point of all U.S. territory** (crosses 180th meridian into Eastern Hemisphere). But by conventional "east = lowest longitude" measure, Maine wins.

Maine facts:

• New England region. Borders: Canada (N/NE), Atlantic (SE), New Hampshire (W).
• Coastline: 3,478 mi (tidal) — "jagged" with peninsulas, islands, fjords.
• Acadia National Park (Mount Desert Island) — Cadillac Mountain = first US sunrise Oct–Mar.
• Forested (90%), lobster, blueberries, timber, tourism.

So: **Maine** for practical purposes; **Alaska** for technical/longitudinal trivia.
