The British Stammering Association (BSA), trading as STAMMA since 2019, is a national membership organisation in the United Kingdom for adults and children who stammer, their friends and families, speech and language therapists and other professionals. It became a charity in 1978 and is based in London.

It describes stammering as a neurological condition and estimates that up to 3% of adults in the UK have a stammer. Organisation The association's chief executive, since June 2018, is Jane Powell.
