Moroccan defender Tahar El Khalej grabbed a late equaliser to earn a point for Southampton at The Valley.
Charlton's Richard Rufus had put the home side ahead but the Saints never gave up and hit back when El Khalej headed home a Jason Dodd cross. The Addicks at least ended a run of four successive Premiership defeats.
They had Chris Powell back in the side, while Southampton were without Chris Marsden and Claus Lundekvam. Southampton suffered an early blow when they lost midfielder Matt Oakley after only eight minutes and he was replaced by substitute Jo Tessem.
Charlton were having the best of the early exchanges and Rufus headed just wide from 12 yards. Rufus put Charlton ahead in the 17th minute with a back header at the near post from a long throw from Robinson. Six minutes later Scott Parker beat the Southampton offside trap but Robinson's lofted pass was just too high for him.
It took Southampton 24 minutes to trouble the Charlton defence but when they did only a superb close-range save from Dean Kiely kept out James Beattie's shot. Charlton's aerial attack had Southampton in trouble again and, after Robinson centred, Jason Euell headed over under the challenge of goalkeeper Jones.
Southampton began the second half with more ambition and Kiely, in the Charlton goal, was forced to react quickly when Delap flicked on a header. But Charlton rode out the spell of pressure, with Rufus heading off the line when Beattie powered in a downward header from just outside the six-yard box.
The home side returned to the attack and when Powell fired in a fierce shot from 20 yards only an excellent one-handed diving save by Jones prevented Southampton from falling further behind. Stuart then had a shot comfortably saved by Jones and at the other end Kiely did well to beat out a superbly struck effort from Beattie.
Rufus almost became the Charlton villain when his misplaced pass enabled Southampton to break but Marian Pahars ran too wide before his shot tested Kiely who saved at the second attempt. Then Kevin Lisbie, who had been on the pitch less than three minutes, was denied a goal when his shot was blocked by the last-ditch interception of El Khalej. A rare Southampton foray ended when Paul Telfer hoisted his long-range lob over the bar.
Lisbie squandered Charlton's best chance to go two-nil ahead when he somehow managed to shoot over the bar from five yards when Johansson's perfectly placed cross presented him with an open goal. Southampton snatched an equaliser with less than five minutes to go when Dodd centred and Kiely was finally beaten by a powerful six-yard header from El Khalej.
