Mostafa Sid Ahmed (Arabic: مصطفى سيد احمد, 1953 – 17 January 1996), also spelled Mustafa Sayyid Ahmad, was a Sudanese singer-songwriter and composer, active from the late 1970s onwards until his death in 1996.

According to an article published during the Sudanese revolution of 2018/19, he was remembered "for performing a selective and expressive type of lyrics that touches upon the causes of ordinary and deprived people.

[2] Sid Ahmed was born in Wad Sulfab village, Al Jazirah State in central Sudan, close to the town of Al-Hasa Hisa.

For example, he had a disagreement with one of the poets who wrote the song "Shagga Al-Ayaam" ("The suffering of the days"), and the argument led to a dispute with the entire Sudanese Musicians' Union.

This style of poetry dealt with the longing for freedom and the struggle of the Sudanese people against the dictatorship that had become especially oppressive during the latter years of the Ja'far al-Numayri regime from 1979 to the early 1980s.

He is absorbed by his thoughts about his family that he loves dearly, but whose needs he is unable to provide for: he thinks of his children’s overly worn clothes, and of his wife’s face as she seeks to console him about their misery.
