Hampartsoum Limondjian (Armenian: Համբարձում Լիմոնճեան; 1768 – 29 June 1839) was an Ottoman Armenian composer of Armenian church, inclined to composition of classical music and Ottoman classical music. He was a musical theorist who developed the "Hamparsum" notation system used as the main music notation for Western Armenian and Ottoman classical music until the 20th-century introduction of European notation systems, and is still in use by the Armenian Apostolic Church.

Limondjian was referred to as Baba Hamparsum (Father Hampartsoum) in Ottoman imperial court music circles. The name Համբարձում, transliterated as Hampartsoum in Western Armenian or Hambardzum in Eastern Armenian, means "ascension".
