The designation distinguishes the counties of Hunterdon, Mercer, Middlesex and Somerset as part of this region.
The recognition of Central Jersey directs the New Jersey Division of Travel and Tourism to begin marketing the area for tourism purposes, including on maps and publications, according to the release.
"Central Jersey is home to some of the nation's leading public universities and host to beautiful agricultural landscapes and activities for tourists to immerse themselves in," Murphy said in the release.
The bill, sponsored by Sen. Andrew Zwicker (D-N.J.) and Assemblyman Roy Freiman (D-N.J.), will go into effect 90 days after the signing.
The bill requires more than 10 percent of the annual funds given to the New Jersey Division of Travel and Tourism to go toward supporting agritourism, which is tourism surrounding agriculture-related industries.
"This legislation is an investment in the future of Central Jersey communities and will strengthen the region's ability to draw new and returning guests," New Jersey Secretary of State Tahesha Way said.
