Mark J. Sokolich (/ˈsɒkəlɪtʃ/ SOK-ə-litch;[1] born 1963) is an American attorney and Democratic Party politician who has served as the mayor of Fort Lee, New Jersey.

Sokolich is of Croatian (possibly from the Istrian region), descent and was raised in Fort Lee.

Sokolich earned a juris doctor from Seton Hall University School of Law,[2] which he attended at the same time as Chris Christie.

Sokolich served on the Fort Lee City Council for four years before being elected mayor in 2007.

It was alleged that this lack of an endorsement led Christie's deputy chief of staff to direct a Christie appointee on the board of the Port Authority of New York and New Jersey to reallocate two of the customary three toll lanes from Fort Lee to the George Washington Bridge, causing massive gridlock.
