The British Armed Forces were militarily involved in Afghanistan between 2001 and 2021 as part of an international coalition in the War in Afghanistan (2001–2021). The United Kingdom was one of the first countries to take part in the American-led Operation Enduring Freedom against the Taliban regime. Its first combat operation was Operation Veritas (2001–02), followed by Operation Herrick (2002–14), which lasted for 13 years and represents the bulk of Britain's involvement. After 2014, the UK held two non-combat missions: Operation Toral (2015–21) and Operation Pitting (2021).

There have been a total of 457 fatalities of British Forces personnel in Afghanistan, including Ministry of Defence (MoD) civilians, during the entire period. The vast majority of fatalities took place after the redeployment of British forces to the Taliban stronghold of Helmand province; before this deployment, only five men had died between April 2002 and early March 2006.

In all, 404 of the fatalities are classed as killed "as a result of hostile action" and 51 are known to have died as a result of either illness, non-combat injuries or accidents, or have not yet officially been assigned a cause of death pending the outcome of an investigation. The Army saw the heaviest losses, with 362 fatalities as of 1 May 2013. Typically those killed were aged between 20 and 29 and the biggest losses seen in 2009 and 2010. Of those killed, 439 were male and three were female.

For the period 1 January 2006 to 31 March 2013 centrally available records show that:

2,116 UK military and civilian personnel were admitted to UK Field Hospitals and categorised as Wounded in Action, including as a result of hostile action. 4,529 UK military and civilian personnel were admitted to UK Field Hospitals for disease or non-battle injuries. 293 UK personnel were categorised as Very Seriously Injured from all causes excluding disease. 298 UK personnel were categorised as Seriously Injured from all causes excluding disease. 6,663 UK personnel were aeromedically evacuated from Afghanistan on medical grounds, for whatever reason.

During August 2002, Sergeant Robert Busuttil and Corporal John Gregory, both aged 30 and both from the Royal Logistic Corps (RLC), were killed. Despite orders rationing beer to just two small cans a day to help prevent such events occurring, Corporal Gregory became involved in a drunken fight with Sergeant Busuttil at a barbecue. Gregory then left the barbecue and returned with a loaded SA80 rifle and killed Busuttil, firing the rifle at him "up to ten times". Gregory then committed suicide with the weapon. The Army was subsequently criticised by Wiltshire coroner David Masters when he recorded verdicts of unlawful killing on the death of Sergeant Busuttil and suicide on Corporal Gregory.
