Żonqor Battery (Maltese: Batterija taż-Żonqor) is an artillery battery in Marsaskala, Malta, standing on high ground overlooking Marsaskala Bay.

Its gun crew and garrison were stationed at the nearby Fort Leonardo.

[3] Soon after being completed, the battery was found out to be inadequate since the range of its RML 7 inch guns did not reach the area of the bay they were supposed to defend.

Due to this, new plans were made to defend the bay by Governor Lintorn Simmons, but these were never implemented.

The battery is believed to have been armed with three canons,[2] but it is said that they may have never been adjusted into place for use.
