There have been 55 official governors of New Jersey, 1 of which were female, with several others acting as governor for a time. In the official numbering, governors are counted only once each, and traditionally, only elected governors were included. However, legislation signed on January 10, 2006, allowed acting governors who had served at least 180 days to be considered full governors. The law was retroactive to January 1, 2001; it therefore changed the titles of Donald DiFrancesco and Richard Codey, affecting Jim McGreevey's numbering. The current governor is Phil Murphy, who took office on January 16, 2018.
