The Guide Dogs for the Blind Association, known by the working name Guide Dogs, is a British charitable organisation formally founded in 1934, three years after the UK's first guide dogs were trained and matched to their owners in October 1931.

Guide Dogs helps blind and partially sighted people across the UK through the provision of guide dogs, mobility and other services for both adults and children. They also campaign for the rights of those with vision impairments and invest in research.

The charity's royal patron is the Countess of Wessex, who succeeded Princess Alexandra of Kent as patron in 2021.

The head office is near Reading in Berkshire. The charity has eight regional centres in Belfast, Cardiff, Forfar, Leeds, Atherton, Leamington Spa, Redbridge and Bristol. The regional centres in Forfar, Atherton, Leamington and Redbridge are also guide dog training schools. There are a further 14 community teams in Edinburgh, Glasgow, Newcastle, Hull, Liverpool, Nottingham, Shrewsbury, Birmingham, Welwyn, central London, Maidstone, Reading (based at head office), Southampton and Exeter. There is also a National Breeding Centre just outside Leamington Spa.

The charity's filed accounts for the year ending December 2019 show income for the year of £122.2million.
