Kırkağaç (Turkish: [ˈkɯɾkaːtʃ]) is a municipality and district of Manisa Province, Turkey.

Olive, walnut, tobacco and almond cultivation is among the important agricultural activities of Kırkağaç.

From 1867 until 1922, Kırkağaç was part of the Aidin Vilayet of the Ottoman Empire.

The Greek writer Elias Venezis, in his book Number 31328, states that Kırkağaç was burned from the Armenian quarter by the "enemy" who left;[5] although this book is a memoir, in later versions, the word "enemy" was changed to "Greek".
