Meanwhile, the visitors will be looking to claim their first league win of the season after losing to Bolton Wanderers in their season opener.
Match preview
Former Luton Town manager Nathan Jones has just begun his first full season as Charlton boss after taking over the reins in February.
After steering the club away from danger last term, Jones would have been pleased to see his side kick off the current campaign with a narrow 1-0 victory over Wigan Athletic, which came courtesy of Lloyd Jones's 81st-minute winner.
Unfortunately for the Addicks, they came out the wrong side of a 1-0 scoreline in Tuesday's EFL Cup clash against Birmingham City, with Brandon Khela's strike condemning them to their third first-round defeat in four seasons.
Charlton may have suffered a midweek defeat at The Valley, but they did finish last season with a seven-game unbeaten home league run.
They will fancy their chances of extending that run on Saturday, have won each of their previous three home league games against Leyton Orient, including a 1-0 win in last season's home meeting.
Leyton Orient experienced a disappointing start to the new season, falling to a narrow 2-1 home defeat in last Saturday's home meeting with Bolton Wanderers.
Charlie Kelman struck in the 38th minute to cancel out Dion Charles's opener, but Leyton Orient could find produce another response when Victor Adeboyejo restored Bolton's slender advantage in the 75th minute.
Leyton Orient boss Richie Wellens would have been disappointed with the opening day result, but he would have been pleased to see his side bounce back with a commanding 4-1 win over Newport County in Tuesday's League Cup tie.
Dan Agyei, Diallang Jaiyesimi, Brandon Cooper and Kelman all got on the scoresheet as the O's breeze past their League Two opponents to set up a second-round tie against Millwall.
The O's will look to build upon that comprehensive victory this weekend as they go in search of their first away league win over Charlton since recording a 1-0 victory in January 2010.

After making a number of changes in midweek, Jones could be tempted to revert back to the same side that started the league win over Wigan.
As for Leyton Orient, Omar Beckles, Jordan Brown and Ollie O'Neil could return to the backline after dropping down to the bench in midweek.
Despite getting on the scoresheet in the EFL Cup, Jaiyesimi may have to settle for a place on the bench against his former club.
