Hartley was born in New Zealand, but qualifies to play for England through his English mother. He moved to Crowborough, East Sussex in 2002 and enjoyed the game through local teams and the Beacon Rugby Academy, where he competed with English, Scottish and Italian rugby hopefuls before being picked for Sussex and later divisional and England schoolboys.
Hartley joined Worcester Warriors academy, representing the senior side just once in the 2004–05 European Challenge Cup. Hartley joined the Senior Academy of Northampton Saints in the summer of 2005.
The following season Northampton won the EDF Energy Trophy and secured promotion from the RFU Championship. Hartley started for Northampton as they defeated Bourgoin in the final of 2008–09 European Challenge Cup. On 22 July 2009, Hartley was made Northampton Saints captain, replacing Bruce Reihana.
Hartley captained the Northampton Saints losing sides in the 2011 Heineken Cup Final and also the 2013 English Premiership Final before going on to lift the trophy the following year when Northampton won the 2014 Premiership final against Saracens.
He has been known as an important lynchpin of the Northampton side with powerful performances in the scrum and in the loose.
On 17 December 2014 Northampton Saints announced that Hartley had extended his contract for a further 3 years, despite a more lucrative offer from French side Montpellier, with Hartley citing his desire to remain playing for his only senior club as a deciding factor.
Hartley received his first cap for England during the 2008 end of year rugby tests against the Pacific Islanders. Hartley made his first start for England against Argentina at Old Trafford in June 2009.
In December 2014 Hartley was banned for another three weeks, bringing the tally over his professional career to fifty weeks. Saints Coach Jim Mallinder has stated that time is running out on Hartley to improve his discipline.
Hartley has also become infamous for his lack of control on the pitch and has been suspended from the game six times for acts of indiscipline. In April 2007 Hartley was banned for 26 weeks for eye-gouging Wasps forwards James Haskell and Jonny O'Connor. Hartley worked with sports psychiatrist Steve Peters. He was banned again in March 2012 for 8 weeks for biting Ireland forward Stephen Ferris in a Six Nations match. Then in December 2012 he was banned for two weeks for punching Ulster hooker Rory Best in a Heineken Cup match. In May 2013 Hartley was sent off in the Aviva Premiership final and banned for 11 weeks after being found guilty of verbally abusing a match official. This act cost Hartley his place in the 2013 British and Irish Lions tour to Australia.
In May of 2015, Hartley disgraced himself again, being found guilty of an off the ball headbutt on Jamie George in the semi-final English premiership loss to Saracens at Franklin's Gardens. He was found guilty by the citing commissioner and banned for four weeks, putting his England Rugby World Cup 2015 selection in jeopardy, as he would be unavailable for the first week of the tournament. 
This is the sixth suspension of Hartley's checkered career in his adopted country.
Hartley is well known for his charity work as an ambassador of the Matt Hampson Foundation as well as captaining a team in Movember 2013, the 'Front Mo Union' which raised in the region of £44,000 for men's health charities.
