Edward John Markey (born July 11, 1946) is an American politician serving as the junior United States senator from the state of Massachusetts, a seat he has held since 2013. A member of the Democratic Party, he served 20 terms (18 full, two partial) as the U.S. representative for Massachusetts's 7th congressional district from 1976 to 2013. Before that, he was a member of the Massachusetts House of Representatives from 1973 to 1976. He is also the dean of the Massachusetts's congressional delegation since 2009 following the death of Ted Kennedy.
In 2013, after John Kerry was appointed United States Secretary of State, Markey was elected to serve out the remainder of Kerry's Senate term in a 2013 special election. Markey defeated Stephen Lynch in the Democratic primary and Republican Gabriel E. Gomez in the general election. He was elected to a full term in the Senate in 2014. Markey fended off a primary challenge from Joseph Kennedy III and was reelected in 2020 by a wide margin.
