The British Tunnelling Society (BTS) is a professional association established in London, UK, in 1971 by tunnelling professionals, led by Sir Harold Harding. The BTS is a learned society of the Institution of Civil Engineers, its mission being to provide a forum for meetings and discussion on tunnel-related matters.

The BTS took part in the founding of the International Tunneling and Underground Space Association (ITA-AITES) in 1974 and represents the UK on its General Assembly. In 2016, the BTS had 800 members making it one of the largest. The current chairman of the BTS, Rod Young, assumed the position in May 2022.

Activities
The BTS provides a forum for meetings and discussion on tunnel-related matters, the BTS also publishes industry guidelines and codes of practice; conducts training courses to advance the education of tunnelling professionals; promotes the recruitment of young people to the industry; acknowledges excellence in tunnelling; sponsors and supports industry conferences; and advises Government and the general public on the art and science of tunnelling. Additionally, the BTS supports the MSc in Tunnelling and Underground Space at The University of Warwick, by advising on the course structure and facilitating lecturers from industry for many modules.

The BTS organises monthly meeting and the BTS Conference & Exhibition and Harding Memorial Lecture every second year. Named after Sir Harding – the founder of the society.

The official magazine of the BTS is 'Tunnels & Tunnelling International' which is currently published monthly by Progressive Media International. The current editor is Patrick Reynolds.

Awards and prizes 
The BTS awards the James Clarke Medal and Harding Prize annually to recognise the achievements of both eminent and young tunnellers respectively.

Harding Prize
Named in honour of Sir Harold Harding, the Harding Prize is awarded annually. The entry to the award consists of an original paper relating to any aspect of tunnelling which the entrant considers to be of interest to others in the tunnelling industry and is open to those aged 33 or younger on 1 January of the same year. The papers are then reviewed by a group of BTS committee members and the writers of selected papers are invited to make an oral presentation to the April BTS meeting. The winner is decided by members of the BTS Committee.

The James Clark Medal
The James Clark Medal is named in honour of James Clark, who worked for Charles Brand and Sons on many well-known tunnels. In 1981 his widow, Madeline, bequeathed a sum of money to provide a medal to be awarded annually to a British Tunneller to perpetuate James' memory. The original criteria were: contemporary achievement in tunnelling; or innovation or responsibility for a large project. In the mid-1980s the medal was not awarded, and with Madeline's approval a third criterion was added: a major contribution to the tunnelling industry. The James Clark Medal is the highest honour awarded by The British Tunnelling Society and has been awarded to:

National Tunnelling Day

The British Tunnelling Society (BTS) announced the UK's first National Tunnelling Day to take place on Thursday, 3 December 2015. The aim of the day is to generate interest in the great number of world class tunnelling projects currently being undertaken in the UK and to promote the industry (and its many professions) to young people and students of all ages. The day will be an annual event occurring on, or in proximity to, the Feast Day of St. Barbara, traditionally seen as the Patron Saint of Tunnellers in the UK.
