The hosts haven't suffered defeat in Sky Bet League One since the beginning of February, whilst they haven't been beaten at The Valley since October.
Six wins from their last eight has put them in a decent position to pinch an automatic promotion spot should any of the clubs above them slip up - whilst a play-off spot is almost mathematically certain.
Mick Harford's side will be looking to make it 29 games unbeaten, following on from last Saturday's fantastic fight back to draw 2-2 with ten men against Blackpool.
Their form throughout March saw Harford win the League One Manager of the Month award, although he made it perfectly clear that it was an award for the entire club, rather than him as an individual.
Tickets for the game at The Valley sold out weeks ago, but the game will be beamed back to Kenilworth Road, which supporters can watch. Click here for all the information.
The Hatters' last win at Charlton came back in 1987, and guess who scored the only goal of the game? Yes, big Mick!
MICK HARFORD SAYS:
On Charlton's game against Wycombe in the week: "I went with Steve Rutter – it was a really good game actually, a really entertaining game. Two teams that were fully at it from start to finish, high tempo, good game of football.
"Charlton are on a good run, they're a good team and have got good players. Wycombe made it difficult for them and it was a game in all honesty that in my opinion could have gone either way.
"Wycombe had lots of chances, Charlton defended well and broke on the counter-attack and looked very dangerous. They're a dangerous team, Charlton."
On the Addicks' form: "Charlton have recruited very well. A big club with big support, looking to get back into the Championship. They're on a good run at the moment. They've got quality strikers, two who look lively. They play a certain way in midfield which enables them to attack very well and they look quite solid at the back. So they're a really good outfit."
WHO?
A Premier League side as recently as 2007, the Addicks have slowly filtered down the EFL pyramid, as this will be their third consecutive season in the third tier. They certainly have aspirations to be at least a level higher though, and it reflects in the history of the club, having spent more seasons in the Championship than any other tier (45).
WHEN AND WHERE?
Kick-off is at 3pm at The Valley on Saturday 13th April.
MAN IN THE MIDDLE?
Tomorrow's game will be overseen by Gavin Ward, who has taken charge of 35 games this campaign, overseeing 114 yellow cards and six red cards.

PLAYED BEFORE?
