Police said the missile was fired from a hand-held grenade launcher at around 4:30 a.m. (0230 GMT).
There were no reports of casualties.
But the attack caused serious damage to the mosque, which is located in the Jasenica area, a Croat-majority suburb that is split between Bosnian Muslims and Bosnian Croats.
"The mosque suffered considerable damage," local Muslim leader Salem Dedovic told Reuters.
He said the blast destroyed the mosque's main entrance, front windows and domes as well as the back windows and facade.
It's worth mentioning that the mosque was built last year on the ruins of an Islamic building damaged in the fighting in 1993-1994 between Bosnian Muslims and Croats.
Imam Salem also said that the missile was fired from a position about 100 meters away from the mosque, adding that the attack occurred minutes before worshippers were due to wake up to eat their pre-dawn meal during the fasting month of Ramadan and then go to the mosque to pray al-Fajr (dawn prayer).
Mostar's mayor, Ljubo Beslic, a Bosnian Croat, denounced the attack and urged citizens to stay calm and help the police find the perpetrator.
Tensions between Catholic Croats and Bosnian Muslims occasionally led to violent incidents in Mostar, which was heavily damaged in the wartime fighting that also destroyed the town's historic 16th century stone bridge.
