General elections were held in Ethiopia on 14 June 1987 for seats in its Shengo. This was the first election since Emperor Haile Selassie was deposed in the Ethiopian Revolution as well as the first election under the 1987 constitution, which replaced the Derg regime with the People's Democratic Republic of Ethiopia (PDRE).

The new Ethiopian Constitution, adopted by a referendum held on 1 February 1987, provided for a national parliament, the Shengo, as the nominal supreme organ of state power. The date of the general elections was officially announced only two days in advance. In the running for the Shengo's 835 seats were some 2,500 candidates, mostly nominated by the Communist Workers' Party of Ethiopia, the country's only legally permitted party. The WPE won 795 seats, with independents taking the remaining 40 seats. Voter turnout was reported to be 90.5%.
