The Prinsens Livregiment (Prince's Life Regiment) is an infantry regiment, one of two in the Royal Danish Army. The regiment is the army's sole line infantry regiment, and is named for Prince Henrik, the husband of Queen Margrethe II. The regiment was formed in 2000 through the amalgamation of the original Prince's Life Regiment with two other regiments:

• Slesvigske Fodregiment - Schleswig Foot Regiment
• Dronningens Livregiment - Queen's Life Regiment

Because one of the regiment's antecedents was the life regiment of Queen Ingrid, the Queen Mother, the regiment has both Prince Henrik's and the late Queen Mother's cypher's on its Regimental Colour. The regiment was founded during the reign of King Frederik III in 1657 under the command of Ernst Albrecht von Eberstein. Over the years it has undergone many changes of name, before being awarded its present one in 1961.

The regiment currently has seven battalions:

• 1st Battalion: Currently serves in the armoured infantry role
• 2nd Battalion: Currently serves in the armoured infantry role
• 3rd Battalion: Currently serves in the mechanised infantry role
• 4th Battalion: Currently serves in the armoured infantry role (Danish International Brigade)
• 5th Battalion: Currently serves in the armoured infantry role
• 6th Battalion: Currently serves in the mechanised infantry role
• 7th Battalion: Currently serves in the mechanised infantry role
