The Syrian-Lebanese Women's Union (al-Ittihad al-Nisa'i al-Suri al-Lubnani) was a women's organization in Lebanon and Syria, founded in the 1920s and active until 1946. It has also been called Lebanese Women’s Union, Syrian Arab Women's Union and Arab Women’s Union. It has been referred to as the starting point of the active women's movement in Lebanon and Syria.
In 1920–21, several Lebanese women's groups formed an informal Union, which was formally established in 1924. It was founded by a group of several pioneering feminists: among them Nour Hamada, Adila Bayhum and Nazik al-Abid. It was established under the leadership of Labibah Thabit.
The purpose of the Union was to function as an umbrella organisation, uniting the women's groups of Lebanon and Syria. It was known as Arab (Lebanese) Women’s Union in Lebanon, and as Syrian Arab Women's Union in Syria. Most of the groups and individuals united under this organisation, were either leftists or secular nationalists.
The Union was a political organisation and hosted conferences and gave speeches and lectures on women's rights. It attended the 11th Conference of the International Woman Suffrage Alliance in 1929, and hosted the First Eastern Women's Congress in 1930.
In 1946, the Union was split in the Women’s Union under Ibtihaj Qaddoura and the Lebanese Women Solidarity Association under Laure Thabet. In 1952, the Women’s Union and the Lebanese Women Solidarity Association were united to form the Lebanese Council for Women, also known as the Lebanese Women's Council.
