The Regency covers an area of 969.36 km2 (excluding the independent city of Mojokerto).

Note: (a) comprising 5 urban kelurahan (Kauman, Mojosari, Sarirejo, Sawahan and Wonokusumo) and 13 rural desa.

The city of Mojokerto, which since 1999 has been administratively independent of the Regency (although the regency administration remains at present centred on the city), virtually divides the regency into two zones - the southern zone comprising the first 14 districts listed above, and the smaller northern zone, comprising the last 4 districts listed above.

One of the more famous locations in Mojokerto is Pacet, which has a good mountainous view.

The biggest Sleeping Buddha Statue in Indonesia is in Maha Vihara Mojopahit Bejijong, Trowulan District, Mojokerto Regency.
