Nancy M. Floreen (born September 29, 1951) is an American politician who was a member of the Montgomery County Council in Maryland from 2002 to 2018, serving four terms.

[10] In 1983, the Montgomery County Department of Environmental Protection allowed Permanent Financial Corporation to build an office building at Wayne and Cedar avenues in downtown Silver Spring that was taller, wider, and closer to the street than county code allowed.

[13] In 1985, the Montgomery County Zoning Board approved construction of a six-story residential building for elders in Silver Spring.

[23] Her candidacy was endorsed by Montgomery County Executive Douglas M. Duncan[24] and the editorial board of the Washington Post.

[41] She also supported banning smoking in restaurants and bars,[42] opposed cutting the Montgomery County Public Libraries' budget,[43] opposed a plan to import lower-cost prescription drugs from Canada for county employees and retirees,[44] and supported a law requiring permits for lawn signs displayed for more than 30 days.

Floreen subsequently switched her party affiliation from Democrat to independent (unaffiliated) and filed to enter the race for Montgomery County executive, submitting 20,343 signatures to election officials by the deadline of August 6, 2018.

She faced Elrich and Republican Robin Ficker, a local attorney and sports heckler, in the November general election.
