Steven Borough (25 September 1525 – 12 July 1584) was an English navigator and an early Arctic explorer. He was master of the first English ship to reach the White Sea in 1553 and open trade with Russia on behalf of the Muscovy Company. He became an expert on piloting in Arctic waters and was one of the earliest English practitioners of the new scientific methods of navigation.[1] He was widely sought out for his knowledge by English and Spanish mariners.
