Kowsar (or Kosar) is a medium-range, land-based anti-ship missile made by Iran. It can defeat electronic jamming systems and "cannot be thrown off course", according to Iranian officials.

The Kowsar designation apparently (Missile Defense Advocacy Alliance 2006) is used to refer to two different missiles: Iranian-produced versions of the PRC C-701 and the TL-10A.

Some news reports indicate that this was the missile used on July 14, 2006 in the 2006 Lebanon War when Hezbollah fired two at Israeli warships. One of the missiles hit the corvette INS Hanit, causing heavy damage and the deaths of four Israeli servicemen. The other missile hit an Egyptian merchant ship causing heavy damage; it is reported that all the crew survived.

Chinese government sources have stated that the missile was not a C-802/Noor. The Hanit did suffer major damage to its steering and some to its engine from the missile hit, and had to be removed from the area, but the damage was lighter than initially feared. Using hits by the Harpoon missile — which has a warhead approximately 1.5 times larger than the C-802, and is generally considered able to cripple a corvette-sized vessel with a single hit — as a reference point, it seems likely that the missiles used by Hezbollah were not Noor missiles, and were the smaller Kowsar. The Kowsar missiles are classed as being able to sink a fast attack craft with one hit, which is more in line with the reported damage.
