The D'Oyly Baronetcy, of Shottisham in the County of Norfolk, was created in the Baronetage of England on 29 July 1663 for William D'Oyly, a supporter of the Royalist cause in the Civil War and Member of Parliament for Great Yarmouth and Norfolk.

The D'Oyly family was descended from Robert d'Ouilly, who came over to England with William the Conqueror.

Warren Hastings D'Oyly, third son of the tenth baronet, was a vice-admiral in the Royal Navy.

Cokayne notes in The Complete Baronetage that a "John D'Oyly" assumed the baronetcy and died in 1781, aged 71; at which point The Annual Register recorded that it "devolves upon Mr. D'Oyly, of Adderbury West", but Cokayne disregards this and states the relationship was not clear.

[15] Furthermore, some earlier histories of the Baronetcy suggested that William D'Oyly, the younger brother of the fourth Baronet, succeeded him, but Cokayne states that this was an "error".
