The Collaborating Political Parties (CPP) was a political alliance in Liberia. The alliance was originally formed in 2018 by four opposition political parties: the All Liberian Party (ALP), the Unity Party (UP), the Alternative National Congress (ANC), and the Liberty Party (LP). It was certified by the National Elections Commission (NEC) in 2020. By February 2022, the ALP and UP had withdrawn the alliance. By March 2022, a large faction of the LP had left as well. In April 2024, the CPP had officially dissolved.
