Vog or VOG may refer to:

• Vog, air pollution resulting from sulfur dioxide emitted by volcanoes
• Video-oculography, an eye-movement measurement technique
• Voices of Gotham, a choir based in New York City, United States
• Volgograd International Airport, Volgograd, Russia
• "Voice of God", industry term for a public address announcer

Vog is a form of air pollution that results when sulfur dioxide and other gases and particles emitted by an erupting volcano react with oxygen and moisture in the presence of sunlight. The word is a portmanteau of the words "volcanic", "smog", and "fog". The term is in common use in the Hawaiian islands, where the Kilauea volcano, on the Island of Hawaii (aka "The Big Island"), has been erupting continuously since January 3, 1983. Based on June 2008 measurements, Kilauea emits 2,000–4,000 tons of sulfur dioxide every day.
