In 2011, Brooksbank began dating Princess Eugenie of York, the younger daughter of Prince Andrew, Duke of York, and Sarah, Duchess of York. On 22 January 2018, the Duke of York's office at Buckingham Palace announced their engagement. In April 2018, the couple moved from their residence at St James's Palace to Ivy Cottage, in the grounds of Kensington Palace. Their wedding took place on 12 October 2018, at St George's Chapel, Windsor. Contrary to press speculation that Brooksbank would be created "Earl of Northallerton", he has not been elevated to the peerage after marrying into the royal family, following a trend in recent years for a male commoner not to be awarded one upon marriage to a princess.
