Marler was educated at Maynards Green Primary School and Heathfield Community College and began playing when 11 for Eastbourne Sharks. His stepping stones in the game not only include playing for Sussex Under 14-18 but also representing London & South East in 2006.
The following season he was again called up into the U20 squad, and marked his 6N debut against Wales with two tries. He made his Guinness Premiership debut for Harlequins at the end of that season.
Marler was initially mostly known for his colourful and creative hairstyles but soon he let his scrummaging and powerful play around the field do the talking. Outside of rugby Joe is interested in cinema, golf and quidditch.
At the start of Harlequins career, Marler was sent out on loan to Esher and Worthing for a season each.
On 18 January 2016, Harlequins announced that Joe Marler had signed a new contract to stay at the club. Marler commented on Twitter: "I'm a Quin. I love everything about the club, good and bad. I love every time I get to pull the famous quarters on."
Marler was called up to the England U20's squad for the 2009 U20 Six Nations, but was injured throughout. He was called up to represent England U20's throughout the Junior World Championship in summer 2009. He was called into the England squad for the 2010 end of year tests as injury cover for David Wilson. When Wilson recovered, Marler was kept on alongside him in the squad. He eventually made his test debut against South Africa where he started two test matches at loose-head prop in the summer of 2012.
Marler started for England against Scotland at Twickenham in the 2013 Six Nations, and was substituted after 55 minutes.
Ahead of England's summer tour to Australia later that year, Marler publicly ruled himself out following recent disciplinary issues. England went on to win this landmark series 3-0.
