Zagreb TV Tower is a 169-metre (563 ft) tall TV tower built of reinforced concrete on the summit of the 1035 metre (3450 ft) tall mountain Medvednica near Zagreb, Croatia.

Zagreb TV Tower was built in 1973. It is not open for the public, although in a 75-metre (246 ft) level there is space for a foreseen tower restaurant.

On October 4, 1991, during the Croatian War of Independence, the tower was a target of a Yugoslav Air Force attack. The tower was bombed at 16:10 and as a consequence the entire fourth and fifth floors and a portion of the third floor sustained heavy damage, rendering the tower unusable. Two staff members present at the time of the attack were not hurt as they took shelter at the base of the tower. It took three months to repair the damage. During that time the television programme was broadcast via several low-power transmitters located within Zagreb itself and atop the Medvednica Mountain. The alternate transmitters were already in position at the time because an attack against the tower was considered possible.[1]

There are some speculations about the opening of the tower restaurant, as a part of the "Sljeme" project, which includes building of the new ski-tracks, and an extension of the cable car line.
