Psalm 122 is the 122nd psalm of the Book of Psalms, beginning in English in the King James Version: "I was glad" and in Latin entitled Laetatus sum. It is attributed to King David and one of the fifteen psalms described as A song of ascents. Its title, I was glad, is reflected in a number of choral introits by various composers.

Song of Ascents is a title given to fifteen of the Psalms, 120–134, each starting with the superscription "Shir Hama'aloth", or, in the case of Psalm 121, Shir Lama'aloth. They are also variously called Gradual Psalms, Fifteen Psalms, Songs of Degrees, Songs of Steps, songs for going up to worship or Pilgrim Songs.
One of the Songs of Ascents, Psalm 122 appears in Hebrew on the walls at the entrance to the City of David, Jerusalem.
