Awit ng Gabi ni Sisa is a Filipino poem written by Jose Corazon de Jesus. It is a dramatic monologue that tells the story of Sisa, a character from Jose Rizal's novel Noli Me Tangere, as she sings a lullaby to her two sons who were taken away from her by the authorities. The poem highlights the theme of motherly love and the agony of a mother who has lost her children to a society that is unjust and oppressive. It also sheds light on the plight of the poor and the marginalized in Philippine society during the Spanish colonial period.
