Sharon Marko (born March 1953) is a former candidate for the U.S. House of Representatives from the Second District of Minnesota.
She ran for the DFL party nomination, opposite Coleen Rowley, but announced the end of her campaign after less than two months, saying she had entered the race too late and that her current duties in the Minnesota Senate didn't leave her enough time to campaign.
Marko's exit left Rowley no significant competitors for the 2nd district DFL candidacy.
Rowley won the candidacy, but lost the general election to two-term incumbent Republican congressman John Kline.
She lives in Surprise, Arizona, where she served as mayor under her married name of Wolcott until she resigned in 2018 for personal reasons.
