Ebubekir Pasha (Ottoman Turkish: ابوبکر پاشا; Turkish: Ebubekir Paşa; 1670 – 1757/1758), also referred to as Koca Bekir Pasha (Turkish: Koca Bekir Paşa) and Abu Bakr Pasha (Bosnian: Ebu Bekir Paša; Greek: Απού Μπεκίρ Πασάς), was an Ottoman statesman. He served as Kapudan Pasha (Grand Admiral of the Navy; 1732–33, 1750–51); as governor (beylerbey) of the provinces of Egypt, Jeddah, Cyprus, and Bosnia; and as head of the Imperial Mint. He was the husband of Safiye Sultan and thus son-in-law (damat) of Sultan Mustafa II.
A great philanthropist, Koca Bekir Pasha was considered one of the most enlightened and productive statesmen of his time.
Ebubekir was born in 1670 in Alaiye (modern-day Alanya, Turkey).
His most notable legacy is the still-standing Kamares Aqueduct, also known as the Bekir Pasha Aqueduct, built in 1746 or 1747 during his tenure as the Governor of Cyprus, which he financed personally to aid the water supply to the area.
