Solan district is one of the twelve administrative districts of the Indian state of Himachal Pradesh. Located in the south-western part of the state, the district takes its name from its headquarters town, Solan, which lies on the Kalka–Shimla highway. The town and surrounding region are sometimes referred to as the "Mushroom City of India" on account of the concentration of mushroom cultivation and research, and as the "City of Red Gold" for tomato production.

The district lies in the lower and middle Himalayan zone, with elevations ranging from the Shivalik foothills to ridges exceeding 2,000 metres. It is bounded by Shimla district to the east, Sirmaur district to the south-east, the state of Haryana to the south, Bilaspur and Mandi districts to the north-west, and the Union Territory of Chandigarh and the state of Punjab to the west. The Giri and Sutlej river systems drain parts of the district. Important towns include Solan, Nalagarh, Arki, Kasauli, Parwanoo, Baddi and Kandaghat.
The territory now forming Solan district historically comprised a number of small princely states of the Shimla and Punjab Hills, including Baghal (with its capital at Arki), Baghat, Kunihar, Kuthar, Mangal, Beja, Mahlog, Bhagal and Nalagarh (Hindur). After Indian independence in 1947, these states were integrated to form the new state of Himachal Pradesh. The Solan area initially formed part of Mahasu district, while Nalagarh was part of Bilaspur district.
Solan district was carved out as a separate district on 1 September 1972, when Himachal Pradesh underwent a comprehensive reorganisation of its districts. It was formed by combining the Solan and Arki tehsils of the erstwhile Mahasu district with the Kandaghat and Nalagarh tehsils of the erstwhile Bilaspur district.
The district is administered by a Deputy Commissioner and is divided into sub-divisions and tehsils that include Solan, Arki, Kandaghat, Nalagarh, Kasauli and Ramshehr, with additional sub-tehsils. For local self-government, the district has a zila parishad along with panchayat samitis at the block level and gram panchayats at the village level. Urban areas are administered through the Solan Municipal Corporation along with several municipal councils and nagar panchayats including Nalagarh, Parwanoo, Baddi, Kasauli and Arki.
Solan has emerged as one of the most industrialised districts of Himachal Pradesh, particularly after the central government extended fiscal incentives to the state in the early 2000s. The Baddi–Barotiwala–Nalagarh (BBN) industrial belt, located in the south-western part of the district, hosts a large number of pharmaceutical, FMCG and engineering units, and is one of the largest pharmaceutical manufacturing hubs in Asia. Parwanoo, on the Haryana border, is another older industrial township with food processing and light engineering industries.
Agriculture and horticulture remain important, with the district being a leading producer of tomatoes, mushrooms, capsicum, ginger, peaches and other off-season vegetables and stone fruits. Tourism contributes to the economy through hill stations such as Kasauli, Chail (partly), Kandaghat and Barog.
Solan hosts several institutions of higher education and research, including:
National Highway 5 (the historic Hindustan–Tibet road, formerly NH-22) passes through Solan, connecting it with Shimla to the north and Kalka and Chandigarh to the south. The narrow-gauge Kalka–Shimla Railway, a UNESCO World Heritage Site, runs through the district with stations including Dharampur, Barog, Solan and Kandaghat. The nearest major airport is at Chandigarh, while Shimla airport at Jubbarhatti lies close to the district's eastern edge.
According to the 2011 Census of India, Solan is among the more populous districts of Himachal Pradesh and records relatively high literacy levels by state and national standards. Hindi is the official language; Pahari dialects, including Mahasu Pahari and Baghati, are widely spoken in the rural areas, with Punjabi spoken in the Nalagarh region adjoining Punjab. Hinduism is the predominant religion, with smaller Sikh, Muslim and Christian communities, the last associated particularly with Kasauli.
