Kings Norton, alternatively King's Norton, is an area of Birmingham, in the county of the West Midlands, England. Historically in Worcestershire, it was also a Birmingham City Council ward within the borough of Birmingham. The district lies 6.5 miles south-southwest of Birmingham city centre and is within 1.5 miles of the north Worcestershire border. Kings Norton has been split into two wards, Kings Norton North and Kings Norton South.

There was Romano-British occupation near the later town. Excavations at Kings Norton found signs of a small Romano-British settlement, including Roman pottery and a Roman ditch at Parsons Hill, near Icknield Street.

Kings Norton derives its origin from the basic Early English Nor + tun, meaning North settlement and belonging to or held by the king, when Kings Norton was the northernmost of the berewicks or outlying manors of Bromsgrove in Worcestershire. Before 1066 these manors with many others in Birmingham had belonged to Earl Edwin, the Anglo-Saxon Earl of Mercia. When in that year a Viking army sailed up the River Humber to invade England, Edwin went to do battle, but was heavily defeated at the Battle of Fulford Bridge near York. King Harold arrived the next day, and after defeating the Vikings at the Battle of Stamford Bridge, immediately marched back south to be himself defeated at the Battle of Hastings. Edwin and his broken remnant of an army were unable go with him. Thus, after the Norman Conquest, when William punished Harold's supporters, Edwin was not amongst them and did not forfeit his lands. Two years later, however, Edwin revolted against William who confiscated his holdings to give as rewards to his followers. Bromsgrove and its berewicks he kept, with himself both as tenant-in-chief and manorial lord. Thus, the manor became Kings Norton remained royal from Domesday until 1804.

Kings Norton was the scene of a couple of minor incidents during the English Civil War. In the first of these, a force led by Prince Rupert of the Rhine, numbering some 300, was resting on Kings Norton Green. There, they were surprised by a smaller group led by Lord Willoughby of Parham. A skirmish took place, in which fifty of Prince Rupert's men were killed, and twenty were taken prisoner. The Parliamentarian force lost twenty men. This took place on 17 October 1642.

In a later incident, Queen Henrietta Maria arrived in Kings Norton with an army of around 5,500 men that she had raised in Yorkshire. It is believed that she stayed the night in the Saracen's Head, while the army camped on land behind the church, now Kings Norton Park (giving rise to the modern road name "Camp Lane"). There is also a public house on this road named The Camp Inn.

In 1616, King James granted permission to hold markets and fairs at Kings Norton. Both the original fairs and the market eventually fell into disuse. At some later date, a mop fair began to be held on the Green on the first Monday of October. A mop fair was a hiring fair where people would go looking for employment. After the decline of hiring fairs, the mop became a village fête organised by the Round Table and raising money for local people. More recently, the Round Table handed over running the mop to a commercial fun fair. A new farmers' market was set up in 2005, operating on The Green once a month.

In 1796, the Worcester and Birmingham Canal was built through Kings Norton, linking Birmingham to the River Severn. This was linked to the Stratford-upon-Avon Canal by Kings Norton Junction, allowing access to Stratford-upon-Avon and, more significantly, the Grand Union Canal. Just beyond the junction is a rare example of a guillotine lock used here as a stop lock.

Discontent with Parliamentary under-representation led to the Priestley Riots in Birmingham 1791, in which buildings including Moseley Hall were burnt down in King's Norton.
