Walter Sisulu Municipality (Xhosa: uMasipala wase Walter Sisulu; Afrikaans: Walter Sisulu Munisipaliteit; Sotho: Masepala wa Walter Sisulu) is a local municipality within the Joe Gqabi District Municipality, in the Eastern Cape province of South Africa.

South of Walter Sisulu lies the Chris Hani District Municipality (DC13).

The municipal council consists of twenty-two members elected by mixed-member proportional representation.

Eleven councillors are elected by first-past-the-post voting in eleven wards, while the remaining eleven are chosen from party lists so that the total number of party representatives is proportional to the number of votes received.

In the 2021 South African municipal elections the African National Congress (ANC) won a reduced majority of twelve seats on the council.
