Happy Entrance[Note 1] was a middling ship of the English navy, built by Andrew Burrell at Deptford and launched in 1619.

[1] King James I originally named the ship Buckingham's Entrance to mark the appointment of his favourite, George Villiers, 1st Duke of Buckingham, as Lord High Admiral of England.

[2] During the Second English Civil War she served on the side of Parliament under the command of Richard Badiley.

In April 1649, a party of seamen from Happy Entrance captured and burnt the Royalist ship Antelope at Hellevoetsluis in the Netherlands.

[4] Happy Entrance was present at the Battle of the Gabbard on the 2–3 June 1653, as part of the Blue Squadron.
