Sheffield Wednesday FA Cup match postponed
An inspection of the playing surface was carried out by match referee Mark Clattenburg at 10:30hrs (local time) and he deemed it unplayable.
No new date for the all-Championship fixture has been announced.
Wednesday are aiming to reach the last eight of the competition for the first time since 1997, while fellow second-tier outfit Charlton have not made it to that stage in eight years.
The sides, who are both in the bottom half of the Championship, drew 1-1 at The Valley in December.
