Several ships have been named Northumberland after the English county of Northumberland, or the Dukedom of Northumberland:

• Northumberland (1797 ship) was launched at South Shields in 1797. She made one voyage for the British East India Company (EIC). She then traded with the West Indies until she wrecked in 1805.

• Ships of the EIC:
  • Northumberland (1763 EIC ship) was launched in 1763 and made four voyages before she was sold. New owners renamed her Lord Shuldam for Lord Shuldham, and hired her out as an armed escort vessel; she was sold for breaking up in 1783.
