Rajapur is a city and a municipal council in Ratnagiri district in the Indian state of Maharashtra. It is 385 km away from Mumbai.

Rajapur has an average elevation of 72 metres (236 feet).

As of 2011 India census, Rajapur had a population of 9,753. Males constitute 50% of the population and females 50%. Rajapur has an average literacy rate of 78%, higher than the national average of 59.5%: male literacy is 82%, and female literacy is 74%. In Rajapur, 9% of the population is under 6 years of age.

During the days of the Bijapur Sultanate, Rajapur was an important maritime trade centre due to a navigable creek that connects it to the Arabian sea. It became an access point to the rich cities of Deccan for those involved in the Arabia-India commerce.

After defeating the Bijapuri general Afzal Khan, Shivaji Maharaj entered the present-day Ratnagiri district and started capturing the important ports and towns. Many Bijapuri generals fled to Rajapur because its governor, known by the title Rustam-i-Zamani, was on friendly terms with Shivaji.

However, Doroji, one of Shivaji's generals, attacked Rajapur. The East India Company had stationed several men in the town, under the charge of Henry Revington to facilitate the trade of saltpeter, pepper, calicoes and cotton. When Rustam-i-Zamani heard about the approach of the Maratha army, he procured funds from one of the company's brokers and escaped with the money in a junk (ship). Revington sent an English ship Diamond to stop him. When confronted by the English, Rustam offered the company the ownership of two of his junks in lieu of payment. At the same time, the Marathas also arrived, and asked the English to hand over the junks to them. The English declined to oblige, unless they were given the money that Rustam owed them. The angry Marathas seized two of the company's brokers, Baghji and Balaji, in Jaitapur. When the English sent Philip Gyffard to demand their release, he was arrested as well. The three prisoners were taken to Kharepatan fort on 18 January 1660.

Henry Revington wrote to Shivaji in February 1660, requesting their release. Meanwhile, the brokers had also pleaded for their release, and Shivaji issued an order to set them free. Shivaji also condemned the attack on Rajapur, dismissed Doroji and issued an order to restore all the loot from Rajapur. However, a rogue officer at Kharepatan refused to set Gyfford free unless he received a bribe. He decided to move Gyfford to another location, escorted by his small Maratha contingent. Revington dispatched an armed party that waylaid the contingent and rescued Gyfford by force.

The East India Company personnel at Rajapur maintained amicable relations with Shivaji until June 1660, when the Adilshahi general Siddi Jauhar attacked Shivaji's camp at Panhala. During this siege, Siddi Jauhar used grenades purchased from the English at Rajapur. He also hired some English artillerymen, who came to Panhala with an English flag, although the Company did not officially support him. Shivaji managed to escape from Panhala, and decided to take revenge as he assumed that the company had supported Siddi Jauhar. He plundered the English factory at Rajapur in December 1661.

During the attack, Shivaji captured four Englishmen - Henry Revington, Richard Taylor, Randolph Taylor and Philip Gyffard - who were imprisoned, first at Vasota and later at Songd. Shivaji's officer Raoji Pandit treated them well, but the Marathas demanded ransom for their release. The English insisted that they had lost everything at Rajapur and would be unable to pay a ransom. Instead, they tried to negotiate their release in exchange for their support in capturing the Danda Rajpuri sea fort. This negotiation could not happen due to the absence of Shivaji, who was away on an expedition near Kalyan. The English prisoners wrote an angry letter to the company's president, who replied that they had been imprisoned not for performing the Company duties, but for illegally supporting Siddi Jauhar without the company's permission. Subsequently, the four made an escape attempt, but they were caught and moved to Raigad.

Later, Shivaji discovered that the company had not officially supported Siddi Jauhar, and that some rogue personnel had joined Jauhar without the company's permission. He ordered the release of the English prisoners in 1663. In a letter dated 6 February 1663, Shivaji also assured that the English would enjoy his protection in the future. The English informed him about the losses suffered by them at Rajapur, and tried to negotiate a settlement. In 1672, Shivaji offered them 5000 pagodas towards the losses. He also promised that if the English decided to set up a new factory at Rajapur, he would "show all kindness and civility imaginable to the said factory". Shivaji was cautious about the British but also wanted to learn the new artillery technology that the British brought.
