Luke Paul Hoare Shaw (born 12 July 1995) is an English professional footballer who plays as a left-back or centre-back for Premier League club Manchester United and the England national team.

Originally a member of Southampton's youth system, Shaw made his first-team debut for the club in January 2012. He signed his first professional contract in May that year before becoming a regular in the Southampton team over the next two seasons. In June 2014, Shaw was signed by Manchester United for £30 million, then a world record transfer fee for a teenager.

Shaw made his senior international debut for England in March 2014 in a 1–0 friendly win against Denmark, and later that year was selected in the squad for the 2014 FIFA World Cup. He scored his first international goal in the UEFA Euro 2020 final, which was also the fastest scored in a UEFA European Championship final.

Luke Paul Hoare Shaw was born on 12 July 1995 in Kingston upon Thames, Greater London, and raised in nearby Molesey, Surrey. He attended Chandlers Field Primary School and Rydens Enterprise School, where he helped the Under-15 team reach the semi-finals of the English Schools' FA Cup. He began playing grassroots football with Hersham and Molesey Juniors. Shaw grew up as a Chelsea supporter and idolised full-back Ashley Cole. He played at Chelsea's development centre in Guildford, but was not offered an academy place. He has said that he wanted to eventually play for the club.

In 2002, Shaw joined the Southampton Academy at the age of seven, and became a regular in the under-18 team from the age of 15. His first association with the first team came in September 2011, when he was an unused substitute in a League Cup match against Preston North End.

During the January 2012 transfer window, it was reported that Premier League clubs Arsenal, Chelsea, and Manchester City had shown interest in signing 16-year-old Shaw, with the then-Championship club reportedly valuing the defender at £4 million. Southampton quickly responded to such claims though, with then-manager Nigel Adkins assuring the media that "Luke Shaw is a big part of our future plans", and claiming that the club had "no intention … of letting any of [their] young players move on".

At the age of 16, Shaw made his debut for the Southampton first team on 28 January 2012 in the FA Cup, replacing winger Jason Puncheon for the final 13 minutes of the third round tie against Millwall, which finished 1–1. Following the club's promotion to the top flight in May 2012, Shaw was one of four youth players offered a professional contract for their return to the Premier League, along with Jack Stephens, Calum Chambers and James Ward-Prowse.

Shaw made his first start for the Southampton first team in August 2012, playing the full 90 minutes of a 4–1 win over Stevenage in the League Cup, and on 10 November 2012, he became the youngest Southampton player to start a match in the Premier League when he was chosen to play at left-back against Swansea City, completing 74 minutes of the 1–1 draw. He continued to make regular appearances throughout the season, and in manager Nigel Adkins's final match as Southampton manager on 16 January 2013, he set up the second goal in a 2–2 draw away to Chelsea, providing a cross from the left wing for Jason Puncheon to convert in the 75th minute. Shaw finished his first professional season with 28 appearances for Southampton, including 25 in the Premier League.
