SCP; Arabic: الحزب الشيوعي السوداني, romanized: Al-Hizb al-Shuyui al-Sudani) is a communist party in Sudan.

In 1971, President Gaafar Nimeiry launched a wave of repression against the party after a failed coup implicated the involvement of a number of communist military officers.

The SCP opposed army colonel Omar al-Bashir's 1989 coup and his subsequent 25-year-long tenure as Sudan's head of state.

The party is opposed to Abdel Fattah al-Burhan's Transitional Military Council and the measures enacted after the 2019 coup.

Pro-Chinese members were either expelled or chose to leave voluntarily to form the Sudanese Communist Party – Revolutionary Leadership.

On 19 July 1971, a group of army officers led by Major Hashem al-Atta launched a coup d'état against the Nimeiry government.

As many of the conspirators were members of the SCP, Nimeiry blamed the party for the coup and executed several of its leaders, including Mahjub and Garang.

[9] Human rights activist Suleman Hamid El Haj was most recently the assistant secretary and spokesman for the party.

[14] The party participated in the 2018–2019 Sudanese protests and demonstrated against the measures enacted by the Transitional Military Council in the aftermath of the 2019 coup d'état.

[4] The party previously supported the policies and positions of the Sudan People's Liberation Movement (SPLM) in the early 1990s.

The freer political climate following the signing of the Comprehensive Peace Agreement has allowed the party to be more active in the country.

Party members suffering during the decades of NIF rule had pleaded with him to be more active but Nugud feared arrest.
