The flag of Malta (Maltese: Bandiera ta' Malta) is a basic bi-colour, with white in the hoist and red in the fly. A representation of the George Cross, awarded to Malta by George VI of the United Kingdom in 1942, is carried, edged with red, in the canton of the white stripe.

The George Cross originally appeared on the flag placed on a blue canton (see List of flags of Malta). The flag was changed on 21 September 1964 with Malta's independence when the blue canton was replaced by a red fimbriation the intention being that the Cross appear less prominent. It also made the flag conform to the western rule of heraldry, which states that no colour may touch a colour, or metal touch a metal (silver/white and yellow/gold being the two metals). The flag has remained unchanged since.

The civil ensign shows a red field, bordered white and charged with a blank Maltese cross.
