The 2014 Socialist Party General Secretary primary elections was held on 28 September 2014, the first primary open for non-members of the Socialist Party (PS). It elected the party's candidate for Prime Minister of Portugal in the 2015 legislative election. It was the first time in Portugal that a party had an open primary. There were only two candidates running: António José Seguro, the incumbent general secretary of the party, and António Costa, the mayor of Lisbon. António Costa won the primary by a landslide, achieving about 68% of the votes against the 32% of António José Seguro.

After the first results were announced, Seguro conceded defeat and resigned as Secretary-General of the Party.^[1]
