The 17th of Ramadan Mosque (Arabic: جامع ١٧ من رمضان, romanized: Jami' Sabata'sh Ramaḍān) is a mosque in al-Rusafa, Baghdad, in the eastern Karrada district, opposite al-Firdos Square, in front of the Ishtar Hotel. The mosque dates back to the royal era of Iraq and is considered an important historical landmark since it is located in a significant square in the city.

The foundation stone was laid during the reign of King Ghazi of Iraq but work did not complete until the 14 July Revolution on July 14, 1959, by Abd al-Karim Qasim and originally gave it the name "Mosque of the Martyr" but despite the opening, prayers did not take place in the mosque until December 6, 1963, during the era of Abd al-Salam Arif in which it was renamed to the "14th of Ramadan Mosque" in honor of the 1963 Ramadan Ba'ath Revolution.

The mosque also has a history of bearing many names, the mosque was originally going to be named "al-Alawiyyah Mosque" but after the 14 July Revolution, it was called the "Republic Mosque." But Qasim wanted to rename it "Mosque of the Martyr" after its opening. On December 6, 1963, the mosque was renamed "14th of Ramadan Mosque."

In 1959, Abd al-Karim Qasim inaugurated the first Monument of the Unknown Soldier in front of the mosque in al-Firdos Square, and to be a shrine for senior political figures who would visit Iraq and lay wreaths there, and with the fluctuations that affected the mosque with its various names, the square remained bearing the name of al-Firdos, then the monument was demolished in 1959. 1981 and it was re-erected in another place and a statue of former President Saddam Hussein was placed in its stead. During the US invasion of Iraq the statue was taken down and the mosque was renamed to its current name to commemorate the Battle of Badr. The square, along with the mosque, became a symbol of the end of an era and the beginning of a new Iraq, however, it also symbolized the chaos that would come after the invasion. Nowadays, the mosque remains active with Friday prayers being held in it for both Sunni and Shi'a Muslims.
