Mulhim ibn Yunus Ma'n (Arabic: ملحم بن يونس معن) was the paramount Druze emir of Mount Lebanon and head of the Ma'n dynasty after succeeding his uncle Fakhr al-Din II in 1633. The Ottomans executed Fakhr al-Din, Mulhim's father Yunus, and his brothers and cousins during and after a massive expedition to end their control over large parts of the Levant. After Mulhim defeated his principal Druze rival, Ali Alam al-Din, in 1641, the Ottomans granted him tax farms previously held by his uncle and father Yunus in southern Mount Lebanon, namely for the subdistricts of the Chouf, Gharb, Matn and Jurd. In 1657 he was appointed governor and tax farmer of Safed. He held onto the tax farms of southern Mount Lebanon until his death in 1658, after falling ill attempting to collect taxes in Safed.

Mulhim and his subordinates, including the Maronite Khazen family of Keserwan, reestablished the core of Fakhr al-Din's former territory. Like his uncle, he maintained good ties with the Maronite Church. He remained on good terms with the authorities throughout most of his career. The tax farms he held were largely inherited by his sons Qurqumaz and Ahmad, the latter retaining them until his death in 1697. Ahmad was the last Ma'nid emir and afterward the dynasty's tax farms and paramountcy over the Druze passed to their Sunni Muslim marital relatives, the Shihab dynasty.

Mulhim belonged to the Ma'n dynasty, a family of Druze traditional emirs of the Chouf region of Mount Lebanon. His father Yunus was one of two sons of Qurqumaz, the Ma'nid chief of the Chouf who died in the 1585 Ottoman expedition against the Druze. The other son was Fakhr al-Din II, who succeeded Qurqumaz in his traditional role around 1591.

Fakhr al-Din gained the Ottomans' good graces and went on to become a powerful tax farmer and governor of the Sidon-Beirut and Safed sanjaks. Because of his increasing strength and autonomy, the Ottomans targeted Fakhr al-Din and the Ma'ns in an expedition in 1613, causing Fakhr al-Din to flee to Tuscany. Yunus largely took over his brother's role, but his power was initially confined to the Chouf. By 1616 Yunus and Fakhr al-Din's son Ali were installed as governors of Sidon-Beirut and Safed. Yunus resumed his role as the deputy of his brother upon Fakhr al-Din's return in 1618.

The Ma'ns expanded their control and tax farms to the Beqaa Valley and much of the Tripoli Eyalet, and their defiance of the Ottomans led to another punitive campaign in 1633. Ali was killed in the fighting, while Yunus was captured along with Mulhim and his brother Hamdan in the Jabal Amil area. Yunus and Hamdan were executed by the commander of the campaign, the Damascus governor Kuchuk Ahmed Pasha, but Mulhim escaped. Fakhr al-Din, meanwhile, was captured and imprisoned in Constantinople.

The Grand Duke of Tuscany Ferdinand II, a political ally and economic partner of Fakhr al-Din, dispatched a galleon to rescue Mulhim, but he was not found. He gained refuge with Ahmad Turabay, the chief of the Turabay dynasty, the Bedouin emirs and governors of the Lajjun Sanjak in northern Palestine. After becoming aware of the fates of Yunus and Fakhr al-Din, Ahmad had his kethuda (steward) escort Mulhim to Kuchuk Ahmed Pasha, but Mulhim escaped en route to Damascus. His residential property in a village called al-Jazira in the southern Beqaa Valley was confiscated and sold by Kuchuk Ahmed Pasha's order in 1634.

While Fakhr al-Din was in prison, a rival Druze chief Ali Alam al-Din was appointed in his place over the tax farms of the Druze areas of Mount Lebanon, namely the Chouf, Gharb, Jurd and Matn districts. Mulhim led the Ma'nid opposition against Alam al-Din. He assaulted Alam al-Din and his forces at a place called Majdel Meouch, forcing their flight to Damascus. Alam al-Din returned with reinforcements and defeated Mulhim at Qabb Ilyas. The Ma'nid afterward went into hiding in the Chouf. His activities prompted the Ottomans to execute Fakhr al-Din in 1635, according to the 17th-century Maronite patriarch and historian Istifan al-Duwayhi.

In 1636 Mulhim and his following drove Alam al-Din out of the Chouf and, together with Assaf Sayfa of Tripoli, went after Alam al-Din and Assaf's nephew Ali as they made their way north. After besieging them in the village of al-Ghantu, they reached a truce and Mulhim returned to his Chouf redoubt. Generally after this victory, Mulhim and his allies among the Druze and Maronite chiefs, including the Khazens of Keserwan, were the stronger party in Mount Lebanon. This paramountcy was interrupted in 1638 when Alam al-Din was reinforced with Shia Muslim allies in Jabal Amil. Mulhim led an ambush against them in the village of Ansar where some 1,600 Shia Muslims were killed.
