Its capital is the town of Cilacap, which had 264,360 inhabitants in mid 2025, spread over three administrative districts.

Cilacap Regency covers a land area of 2,323.93 km2 (including the 115-km2 Nusakambangan Island off the south coast), and it had a population of 1,642,107 at the 2010 Census and 1,944,857 at the 2020 Census; the official estimate as of mid 2025 was 2,046,392 (comprising 1,029,948 males and 1,016,444 females). The languages used in Cilacap are Javanese and Sundanese, although most people can speak Indonesian; the dialect of Javanese used is Banyumasan.

There are schools of all levels in Cilacap and several higher-learning institutions. Several academies exist, such as Akademi Maritim Nusantara (National Maritime Academy). A polytechnic, Politeknik Cilacap, was established in 2008 and offers Engineering, Electronics and Informatics education.

Cilacap Town

Cilacap's power plant provides 600 megawatts of electricity

The town of Cilacap is also a sea port on the southern coast of the island of Java. The port is one of only a few that exist on the southern coast that can service shipping of reasonable tonnage. The nearest safe anchorage east is Pacitan. The city's harbor is protected by Nusakambangan, an island best known as the site of several high-security correctional facilities although there are also hopes that the island can be developed as a tourist hub. Nusakambangan sheltered Cilacap from the worst of the 2004 tsunami. Nevertheless, the disaster took 147 lives, devastated beaches, damaged 435 fishing boats and inflicted material losses amounting to about Rp 86 billion (around $9 million).

During World War II Cilacap was an important departure point for people fleeing the Japanese invasion, especially Dutch colonists. Many left the Dutch East Indies by boat or seaplane, the majority heading for Broome in Western Australia.

The port is a hub for national or international trade. The town's Tunggul Wulung Airport provides scheduled airline services to Jakarta and Semarang.

Cilacap is the site of many industrial plants, a geothermal power plant, a cement plant (Holcim Indonesia), and one of Pertamina (Indonesia's national petroleum company) processing units in Indonesia. The site has the largest production capacity, producing the most diverse kinds of products among other Pertamina units.

The town of Cilacap offers several tourist attractions highlighting Banyumasan culture. The town has a number of beaches, two of the most popular being Teluk Penyu (close to the center of town), but these are somewhat fouled from leakage of the shipping vessels docked adjacent to this and Widara Payung. Nearby the Teluk Penyu beach is also an old Dutch fortress called Benteng Pendem. This fortress was built in stages during 1861-1879 by the Dutch East Indies Army.

The three administrative districts (kecamatan) which together comprise the town of Cilacap are sub-divided into the following fifteen urban villages (kelurahan), listed below with their areas and their populations according to the mid-2023 official estimates. The first five listed comprise South Cilacap District, the next five comprise Central Cilacap District, and the last five comprise North Cilacap District.

Segara Anakan Bay

In early 2012 Segara Anakan Bay's area was only 600 hectares, reduced from 700 hectares in 2005 after dredging. Heavy sedimentation from the Citanduy River (which is located on the border of Ciamis Regency and Cilacap Regency) caused it. To overcome the sedimentation in Segara Anakan Bay, Ciamis Regency agreed to a new canal from the Citanduy River passing through their area and exiting at Nusawiru near Pangandaran Beach.

Climate

Cilacap has a tropical rainforest climate (Af) with heavy to very heavy rainfall year-round. In November 2025 heavy rains resulted in landslides. The following climate data is for the town of Cilacap.
