Urmston /ˈɜːrmstən/ ^ⓘ is a town in Trafford, Greater Manchester, England, which had a population of 41,731 at the 2021 Census. Historically in Lancashire, it is 5 miles (8.04672 km) southwest of Manchester city centre. The southern boundary is the River Mersey, with Stretford lying to the east and Flixton to the west. Davyhulme lies to the north of the town centre. Urmston covers an area of 4,799 acres (1,942.08639710976 ha).

The town has early medieval origins, and until the arrival of the railway in 1873 was a small farming community. The railway acted as a catalyst, transforming the town into a residence for the middle classes.

In 1986 during an excavation by South Trafford Archaeological Group, fragments of Roman pottery were found in the area now occupied by the cemetery – previously the site of Urmston Old Hall – suggesting that there may have been a Roman settlement on the site. In the early 13th century, Lord Greenhalgh and his family lived at Highfield House (under what is now the M60 motorway).

Shortly after the Norman Conquest of England, between 1069 and 1070, William the Conqueror led a military campaign against the Saxon Earl Edwin, who ruled England north of the River Mersey. On the campaign's successful conclusion, William gave his kinsman Roger de Poictou all of the land between the River Mersey and the River Ribble. Part of this land was in turn given to Albert de Greslet, who towards the end of the 12th century, bestowed as much land as a team of oxen could plough in one-year on Orme Fitz Seward, the son of Edward Aylward. It is probable that the name Urmston is derived from Orme's Easton, or Ormestun, the "tun" or dwelling of Orme Fitz Seward.

The Manor of Urmston was rented by a family using the local surname. The earliest known member of the Urmston family is Richard de Urmston, who was recorded in 1193–94 as giving 40 shillings "for having the king's good will". Orme Fitz Seward's land passed to Richard de Trafford in the 13th century. The de Trafford family later lost the land, but won it back as the result of a duel.^{[citation needed]}

Urmston Old Hall was the home of the manorial lord, and a centre of power in the area during the Middle Ages. The Old Hall was completely rebuilt in brick and timber in the late 16th century. New Croft Hall, also in Urmston, was the residence of a wealthy freeman and may have been moated. Urmston was only one of three manors in Trafford to have had two medieval halls, the others being Hale and Timperley. Neither of the halls has survived to the present day. The modern-day descendants of the original inhabitants are still living locally, Both Lord M Gatward Snr and Jnr still reside in the area and can often be seen on horseback riding through their land close to the centre.

Farming was the main occupation in Urmston until the early 19th century, when weaving became a significant source of employment, although this later declined due to competition from large industry. In 1848, the population was recorded as being 771, with around 80% of the land being farmed. The opening of the Cheshire Lines Railway in 1873 allowed the town to grow as a commuter town: between 1871 and 1901 the population grew by over 650%, from 996 to 6,594. By 1901, farming had virtually died out, and the town became a residence for the middle classes.

In 1948 the Minister for Health, Aneurin Bevan, conducted the symbolic inauguration of the National Health Service at Davyhulme's Park Hospital, now renamed Trafford General Hospital.
