Íñigo Errejón  is a Spanish political scientist and politician, serving as member of the 14th Congress of Deputies.

Doctor of Philosophy in Political Science, he was the secretary for policy and strategy and campaigning of Podemos (managing several electoral campaigns of the political party) as well as a member of the 11th and 12th terms of the Congress of Deputies. He split from Podemos and founded a new platform in early 2019, Más Madrid, under which Errejón was elected to the Assembly of Madrid and that was later re-constituted as Más País in order to run in the November 2019 general election, with the outcome of Errejón returning to the Congress of Deputies.
