Lavinia Mary Fitzalan-Howard, Duchess of Norfolk (née Strutt; 22 March 1916 – 10 December 1995) was a British noblewoman.

On 27 January 1937, she married Bernard Fitzalan-Howard, 16th Duke of Norfolk at the Brompton Oratory.

In 1953, she took the part of Queen Elizabeth II during dress rehearsals for the coronation at Westminster Abbey.

The Duke of Norfolk was hereditary Earl Marshal and organised both coronations as well as important state events in later years.

For many years, the traditional curtain-raiser to the English international cricket season was a match between Lavinia, Duchess of Norfolk's XI and the visitors, played at Arundel Castle.
