Pen (Marathi pronunciation: [peːɳ]) is a town and taluka in Raigad district of Indian state of Maharashtra.

In 1819 the easy communication with Bombay and with the Deccan by the Bor pass made Pen an important centre.

A number of carved stones about the town appear to belong to an unusually large temple of about the thirteenth or fourteenth century.

Very Old Temple of Lord Shiva located in the Jungle of Wagreshwar in Mahal Mirya Donger In Chhatrapati Shivaji Maharaj era, Shayistekhan's raid on Deccan led to major fights in Pen between Moghals and Marathas.

Initially the Moghal army led by Sardar Taherkhan occupied Pen's fort of Mahalmeera and looted surrounding villages, which included desecration of the grand temple of Goteshwar.

Mahalmeera was also taken back on 27 February 1662 and the following day, after a valiant struggle, Pen's Bastion (presently, the site of Tehsil office) was secured by Shivaji's army.

[8] It gained prominence in ancient times due to its location on trade routes to Deccan, proximity to Mumbai and Pune and its central position in the Raigad district.

[10] The Pen Municipal Council has population of 37,852 of which 19,257 are males while 18,595 are females as per report released by Census India 2011.

[chk] Traditionally, Pen city was populated by Aagri, Brahmins and merchant's community as it was center of culture, education and trade.

Reliance Industries was promoting a Maha Mumbai Special Economic Zone, located around the town.

A study conducted by Citizen's Research Collective on SEZ has called the Maha Mumbai Special Economic Zone a Special Exploitation Zone[16] Land owners resisted the purchase of their land for the purpose and following a historic referendum on the issue, SEZ was cancelled.

In fact, Lokmanya Tilak used to call it "कोकणचे पुणे"(Pune of Konkan) due to progressive mindset of Penkars and their love of knowledge.

Balkrishna Shankar Karandikar started an industrial training school around this time; the Kokan Vidyalaya, which was later closed as a result of his arrest for involvement in Jackson's shooting at Nasik in 1909.
