Hashem Safieddine (Arabic: هاشم صفي الدين, romanized: Hāshim Ṣafī al-Dīn; 1964 – c. 3 October 2024) was a Lebanese Shia cleric who served as the head of Hezbollah's Executive Council from 2001 until his assassination in 2024.

[9][10] In 1995, Safieddine was promoted to the Majlis al-Shura (Consultative Assembly), the highest council in Hezbollah,[8] after which he operated under Imad Mughniyeh, until the latter's assassination in 2008.

[29] In 2020, the U.S. sanctioned two Lebanon-based companies, Arch Consulting and Meamar Construction, which are both subordinate to the Executive Council of Hezbollah,[30] receive guidance and direction from Safieddine and Sultan Khalifah As'ad,[31][32][33] and are accused of concealing money transfers to the accounts of Hezbollah leadership, "while the Lebanese people suffer from inadequate services".

[30][33] After Nasrallah was killed in an Israeli airstrike on Hezbollah's headquarters in September 2024, Safieddine was widely expected to be named as his successor.

[34][6] He was recognized for his similarity to Nasrallah in both appearance and manner of speaking,[4] and for his strong ties with the Iranian regime and the Ayatollah.

[27] In the immediate aftermath of Nasrallah's death, the Saudi news outlets Al Arabiya and AlHadath reported that Safieddine had been officially designated as his successor, although Hezbollah denied this via Telegram.

[6] On the night of 3 October 2024, an Israeli Air Force strike targeted Safieddine at a location in Dahieh, a Beirut suburb that is a Hezbollah stronghold.

[36][2][37][38] The airstrike targeted an underground bunker[38] at which Hezbollah intelligence chief Hussein Hazimah ("Mortada") was also believed to be located.
