Bab Tuma (Arabic: بَابُ تُومَا, romanized: Bāb Tūmā, meaning: "Gate of Thomas") is a neighborhood located in the Old city of Damascus in Syria.

The Damascus affair happened in 1840, near Bab Tuma, when an Italian monk & his servant disappeared.

The Christians accused the Jews of their disappearance, saying they extracted their blood to bake matzo.

French noble, Alphonse de Lamartine visited Bab Tuma in 1832.

It was also visited by German emperor Wilhelm II and his wife, Augusta Victoria of Schleswig-Holstein in 1898.
