Seif Sharif Hamad (22 October 1943 – 17 February 2021) was a Tanzanian politician who served as the First Vice President of Zanzibar and as Party Chairman of ACT Wazalendo.

After completing high school in December 1963, for the next nine years (1964–1972), he was prevented from pursuing university education because he was required to fill in one of the vacancies in the civil service caused by the mass departure of British officials in 1964,[3] after being asked to do so by the new Zanzibar Revolutionary Government.

[7] When Tanzania adopted a multiparty political system in 1992, Hamad along with other former CCM members founded the Civic United Front party.

Observers condemned the poll citing widespread irregularities and instances of intimidation of opposition supporters by the security forces.

[citation needed] On 26 and 27 January 2001, more than forty five CUF supporters were gunned down by Tanzanian Security Forces in peaceful demonstration called to protest the imposition of Zanzibar Government against the will of the people.

This led to the ruling CCM party and opposition CUF to have a dialogue that resulted in signing MUAFAKA II, a peace accord designed to ensure electoral and constitutional reforms.

Most of the planned reforms were not implemented by the government, including, crucially, an agreed credible voters' register prior to the elections of October 2005.

[9] In May 1989, he was arrested and taken to court to face (politically motivated) trumped up charges of allegedly being found with government secret documents.
