Henry Bourchier, 5th Baron Bourchier, 2nd Count of Eu, 1st Viscount Bourchier, 1st Earl of Essex, KG (c. 1404/c. 1406 – 4 April 1483), was the eldest son of William Bourchier, 1st Count of Eu and Anne of Gloucester. On his mother's side, he was a great-grandson of Edward III of England.
He inherited the title of 5th Baron Bourchier from his cousin Elizabeth Bourchier, 4th Baroness Bourchier on her death in 1433. He became the 1st Viscount Bourchier in 1446, a Knight of the Order of the Garter in 1452, and was created 1st Earl of Essex in 1461.
He saw considerable military action in France and for his services was created Viscount Bourchier during the parliament of 1445–6 and elected Knight of the Garter on his third nomination in 1452. He later saw action in 1461 as a Yorkist supporter at the Second Battle of St Albans and the Battle of Towton, soon after which Edward IV created him Earl of Essex.
He held the post of Lord High Treasurer from 29 May 1455 - 5 October 1456, 28 July 1460 - 14 April 1462, and 22 April 1471 - 4 April 1483. He also became Justice in Eyre south of the Trent in 1461, holding that title until his death.
He died on 4 April 1483 and was buried at Beeleigh Abbey, although his tomb was subsequently moved to Little Easton church.
