Solan is a city and the administrative headquarters of Solan district in the Indian state of Himachal Pradesh. Located in the lower Himalayan range, the city lies on the Kalka–Shimla highway (National Highway 5) and is a notable urban centre between Chandigarh and Shimla. It is sometimes referred to as the "Mushroom City of India" on account of large-scale mushroom cultivation in the area, and historically as the "City of Red Gold" for its tomato produce.

Solan is situated in the Shivalik foothills at an elevation of roughly 1,500 metres above sea level. The town is set in a valley flanked by hills, with the Ashwini Khad and Giri tributaries draining the surrounding terrain. The climate is sub-temperate: summers are mild, the monsoon is active from July to September, and winters are cold with occasional snowfall on the higher ridges. The pine and oak forests surrounding the city are characteristic of the lower Himalayan belt.
The name of the town is commonly traced to the goddess Shoolini Devi, whose temple stands in the city. An annual fair known as the Shoolini Mela is held in her honour and is among the principal cultural events of the region.
The area was historically part of the princely state of Baghat, one of the Shimla Hill States under British paramountcy. After Indian independence in 1947, the Shimla Hill States were integrated into the Indian Union and became part of the Chief Commissioner's Province of Himachal Pradesh in 1948. Solan district was carved out on 1 September 1972 through the reorganisation of districts in Himachal Pradesh, combining tehsils from the erstwhile Mahasu and Shimla districts, with Solan town designated as the district headquarters.
The economy of Solan combines horticulture, agro-processing, education, tourism, and industry.
Solan hosts several institutions of higher learning and research:
Civic affairs are managed by the Solan Municipal Corporation. The city is also the seat of the district administration, including the Deputy Commissioner's office, district courts, and the Superintendent of Police.
Solan is well connected by road via NH 5, which links Zirakpur and Shimla. The city is a station on the Kalka–Shimla narrow-gauge railway, a UNESCO World Heritage Site inscribed in 2008 as part of the "Mountain Railways of India". The nearest airport is Shimla Airport at Jubbarhatti, while Chandigarh International Airport serves as the principal gateway for long-distance air travel.
Solan's role extends beyond its size: as the gateway between the plains of Punjab and Haryana and the hill state of Himachal Pradesh, it functions as an administrative, educational, industrial, and horticultural hub. The presence of the BBN pharmaceutical cluster has made the district one of the largest contributors to Himachal Pradesh's industrial output.
