Lady Helena Gibbs (Helena Frances Augusta; formerly Cambridge; 23 October 1899 – 22 December 1969), born Princess Helena of Teck, was a relative of the British royal family. She was a great-great-granddaughter of King George III and a niece of Queen Mary and King George V.

Born at Grosvenor House, Mayfair, Westminster, she was the second daughter of Prince Adolphus of Teck (later Adolphus Cambridge, 1st Marquess of Cambridge) and Lady Margaret Grosvenor (later Marchioness of Cambridge).

During the First World War, members of the British royal family and their close relatives including the House of Teck, relinquished their German titles. Helena then assumed the style Lady Helena Cambridge.

She married Colonel John Evelyn Gibbs in 1919 and was subsequently known as Lady Helena Gibbs. She died in 1969.
