A new feature where we take a closer look at who Rovers will face in League One next season.
Nickname: The Addicks
Founded 112 years ago this week, when a number of youth clubs combined, the London club turned professional in 1920 and first entered the Football League a year later.
Since then, they have had four separate spells in the top flight - 1936-1957, 1986-1990, 1998-1999 and most recently from 2000-2007.
With the exception of their Premier League years, the most successful period in the club's history was during the 1930s, when they recorded their highest league finishes, including runners-up spot in the First Division in 1937.
During the post-war years, the club have twice reached the FA Cup final, losing 4-1 to Derby County in 1946 and lifting the trophy by beating Burnley 1-0 at Wembley 12 months later.
The Manager: Karl Robinson
Formerly an Academy coach at boyhood club Liverpool, Karl Robinson joined Rovers' backroom team under Paul Ince as assistant first team coach in the summer of 2008.
Following Ince's dismissal - and the subsequent arrival of Sam Allardyce - Robinson was promoted to first team coach that December.
Robinson left Rovers in July 2009 to be reunited with Ince at League One side MK Dons, where he took up the role of assistant manager.
In May 2010, Robinson was appointed manager of MK Dons, making him the youngest manager in the Football League at the time, aged just 29.
He guided the Dons to the League One play-offs in his first season in charge, losing out 4-3 to Peterborough United in the semi-finals.
A year later, Robinson again led the Dons to a fifth-place finish, but again suffered play-off heartache, losing 3-2 to Huddersfield Town over two legs.
Success that the Dons fans craved eventually arrived in 2014-15, as Robinson's side finished runners-up in League One, securing promotion to the Championship for the first time.
However, their stay in the second tier would be short-lived, as the Dons were relegated back into League One at the end of the 2015-16 season.
In October 2016, Robinson was relieved of his duties at stadium:mk and was appointed manager of Charlton Athletic a month later.
The Ground: The Valley
The 27,111-capacity stadium, which is located in south east London, has been home to Charlton Athletic since 1919.
The club did, however, spend one season (1923-24) in Catford and seven years playing at Crystal Palace and West Ham United's grounds between 1985 and 1992.
Rovers Ladies played their FA Women's Premier League championship play-off final at The Valley last month, losing 3-0 to Spurs.
Last season: 13th, League One
Relegated from the Championship in 2015-16, Charlton finished 13th in their first season back in the third tier since being crowned champions in 2011-12.
The season started with newly-appointed boss Russell Slade at the helm, but the former Cardiff City chief lasted less than six months and was sacked in mid-November having won just four of his 16 league games in charge.
Karl Robinson was brought in to replace him and steered the club to a mid-table finish.
In the cup competitions, Charlton suffered an early exit from the EFL Cup at the hands of League Two Cheltenham Town and lost out to Robinson's former club MK Dons in the FA Cup at the second round stage.
Last Meeting: January 23rd 2016
Jordan Rhodes scored on the stroke of half-time to cancel out Harry Lennon's opener, as Rovers were held to a 1-1 at The Valley by a Charlton side who would go on to be relegated.
