Utqiagvik officially the City of Utqia?vik, formerly known as Barrow, is the largest city (and the borough seat) of the North Slope Borough in the U.S. state of Alaska and is located north of the Arctic Circle. It is one of the northernmost public communities in the world and is the northernmost city in the United States. Nearby Point Barrow is the country's northernmost point.

The sun sets on November 18 or 19, and it remains below the horizon for about 66 days. This creates a polar night that lasts until the Sun returns to lightly touch the horizon (due to the refraction and scattering of the atmosphere) by January 22 or January 23. The sun then rises again completely over the horizon by January 27 or 28. During the first half of the polar night, there is a decreasing amount of twilight each day, and on the winter solstice (around December 21 or December 22), civil twilight in Utqia?vik lasts for a mere 3 hours.

In addition to its low temperatures and polar night, Utqia?vik is one of the cloudiest places on Earth. Owing to the prevailing easterly winds off the Arctic Ocean, Utqia?vik is completely overcast slightly more than 50% of the year. It is at least 70% overcast some 62% of the time. Cloud types are mainly low stratus and fog; cumuli forms are rare. Peak cloudiness occurs in August and September when the ocean is ice-free. Dense fog occurs an average of 65 days per year, mostly in the summer months. Ice fog is very common during the winter months, especially when the temperature drops below ?30 °F (?34 °C).
