Mġarr ix-Xini (Maltese: Imġarr ix-Xini), is a bay close to Għajnsielem (southwest), Xewkija and Sannat (southeast) on the Maltese island of Gozo.

It lies in a gorge to the west of Mġarr Harbour, accessible mainly from the nearest village of Xewkija as well from Sannat.

A small watchtower was built to defend the area in 1661, and it was restored several times in recent years.
