The news that Raida Muhammad Wajih Wazan had been abducted came the same day that two Indonesian journalists were released.
Wazan, who works for a branch of the local station Iraqiya, was taken by several masked armed men on Sunday night while she was returning to her house in Mosul's al-Shahwan neighbourhood, said an official on Monday.
No other details were immediately available.
Last Wednesday, half a dozen mortar rounds were fired at the Mosul TV station, wounding three technicians working there.
An Arabic-language internet bulletin board carried a statement from a group in Iraq alleged to be affiliated to al-Qaida claiming responsibility for the mortar strike, but there was no way to verify the veracity of the claim.
