The district is named after its administrative headquarters, Sonipat. Sonipat was earlier known as Sonprastha, which later becameSvarnaprastha (Golden City), which is derived from two Sanskrit words, Svarna (Gold) and Prastha (Place). Over a period of time, the classical name Svarnprastha’s pronunciation degraded into Svarnpat, and then to its current form, Sonipat.
