Mukaththir ibn ‘Īsá ibn Fulaytah al-Ḥasanī al-‘Alawī (Arabic: مكثر بن عيسى بن فليتة الحسني العلوي; d. 1203–1204) was the last Emir of Mecca from the sharifian Hawashim dynasty, reigning at least three times between 1176 and 1203.
On 2 Sha'ban 570 AH (c. 5 March 1175) Mukaththir's father died, and his brother Da'ud became Emir of Mecca.
Less than a year later, on the night of 15 Rajab 571 AH (c. 5 February 1176), Mukaththir deposed his brother and assumed the Emirate.
In Dhu al-Hijjah of that year (June 1176) the Iraqi amir al-hajj Tashtakin al-Mustanjadi arrived with orders from the Caliph to depose Mukaththir.
He writes that in that year Da'ud looted the Kaaba of its wealth and stripped the Black Stone of its silver collar.
