The Eastern Province is one of the four provinces of Sierra Leone. It covers an area of 15,553 km². Its capital and administrative centre is Kenema. Eastern Province, the centre of the country's diamond mining industry, is very mountainous and has two ranges, the Gola Hills and the Loma Mountains.

The Eastern Province is the heart of Sierra Leone's diamond mining activity. The precious stone was first discovered in around the 1930s and has played a major part in the region's history ever since. Most diamonds are mined and exported by small local enterprises, numbering around 200,000 to 300,000; some of these are illegal, while many are officially sanctioned. Additionally, there are a handful of foreign countries carrying out larger scale diamond mining.

The Eastern Province borders the Nzérékoré Region of Guinea to the northeast, the Liberian counties of Lofa, Gbarpolu and Grand Cape Mount to the east and south, and the Sierra Leonian Southern and Northern provinces to the west and northwest. Eastern Province is the only region of Sierra Leone without any shoreline.

The province is divided into 3 districts. They are the Kailahun District, based around the city of Kailahun; the Kenema District, which is headquartered by the provincial capital Kenema; and the Kono District, headquartered at Koidu.
