The 2nd Infantry Division, Queen's Guard (Thai: กองพลทหารราบที่ 2 รักษาพระองค์) (พล.๒ รอ.) is an infantry division of the Royal Thai Army. It is currently part of the First Army Area. The division was founded by King Chulalongkorn (Rama V) in 1910. In 1988 the division was designated a King's Guard unit by cabinet order, however, as a mark of distinction the division and all its subsidiary units were put under the patronage of Queen Sirikit and has since been known as the Queen's Guard.

The division is composed of three infantry regiments and three attached units, the 2nd Infantry Regiment, Queen's Guard, the 12th Infantry Regiment, Queen's Guard, and the 21st Infantry Regiment, Queen's Guard. The division and its subsidiary units are all based east of Bangkok, headquartered in Prachinburi, with other units in Chonburi and Sa Kaeo.

The 2nd Infantry Division was formed in 1910 at the command of King Chulalongkorn, as a part of the newly reorganised Siamese army. After the Siamese revolution of 1932 the new administration temporarily dissolved all formations above battalion level, including the 2nd Infantry Division. During the Franco-Thai War of 1940-1941, the division's former components were incorporated into the Burapha Army (Eastern army), as the 2nd Division on the orders of Field Marshal Plaek Phibunsongkhram. The division remained part of the army during the Burma Campaign and supported the Phayap Army's invasion of the Shan States. After the end of the war the division was once again dissolved in 1946, this time due to budget cuts. Its headquarters was absorbed into the 2nd Infantry Regiment.
