The Military Star (Irish: An Réalt Míleata) is a military decoration awarded to those members of the Irish Defence Forces or Chaplaincy Service who were killed or mortally wounded in the line of duty as a result of hostile action by an armed enemy.

The medal is bronze and takes the shape of an eight-pointed star 35 mm (1.4 in) wide.

The reverse is blank so that the deceased soldier's name, army number, and date and location of death may be engraved.

[1] The ribbon is suspended at the top from a bronze bar bearing the word, in relief, REMEMBRANCE.

[1] The medal and ribbon were designed by Corporal Dan O'Connell, Defence Forces Ceremonial (now retired).
