It has a total land area of approximately 1,812.8 km2 (699.9 sq mi) or + 3.78% of the area of East Java Province. With a length of 47 km (29 mi) along the coastline (comprising Paciran and Brondong Districts), the sea area of Lamongan Regency is about 902.4 km2 (348.4 sq mi), if calculated to a distance of 12 miles (19 km) across the ocean surface.

The regency seat is the town of Lamongan, situated on the Solo River which passes from west to east through the regency, effectively dividing it in two. There are three main geographic divisions. In the far south of the regency (Sukorame, Bluluk, Ngimbang, Sambeng, Mantup and Modo Districts), and also in the northern coastal area (Brondong, Paciran and Solokuro Districts) are limestone mountains with land of medium fertility. Between the coastal uplands and the Solo River, much of the region consists of 'bonorowo' wetlands prone to periodic flooding (chiefly Glagah, Karangbinangun, Turi, Kalitengah, Karanggeneng, Laren, Maduran and Sekaran Districts). The remaining areas close to and south of the Solo River comprise lowlands of limited fertility (Kembangbahu, Sugio, Kedungpring, Babat, Pucuk, Sukadadi, Lamongan, Tikung, Sarirejo and Deket Districts). Lamongan Regency is bordered by: Northern side : Java Sea Southern side : Mojokerto Regency and Jombang Regency Eastern side : Gresik Regency Western side : Tuban Regency and Bojonegoro Regency The economy is mainly supported by agriculture, fishery, and commerce, especially the home industry.
