Sadhu Singh Bhaura (Punjabi: ਸਾਧੂ ਸਿੰਘ ਭੌਰਾ) (6 June 1905 – 7 March 1984) was a Sikh missionary who served as the 21st Jathedar of the Akal Takht from 1964 to 1980.
After matriculating from Khalsa High School, Lyallpur (where Master Tara Singh, later a leading figure in Sikh politics, was the headmaster), he joined police service and served at Quetta from 1923 to 1925 before resigning to take part in the Akali agitation for Gurdwara reform.
In 1964, Sadhu Singh Bhaura was elevated to the position of Jathedar of Sri Akal Takht, the highest seat of religious authority and legislation for the Sikhs.
He attracted wide public notice when, on 10 June 1978, he issued a hukamnama or edict calling upon all Sikhs to boycott socially the neoNirankari sect.
In 1980, Jathedar Sadhu Singh Bhaura, in an effort to avert a vertical split in the Akali Dal, formed a seven member committee of senior party leaders to function as collegiate executive, but soon after himself resigned on health grounds and retired to live with his sons in Jalandhar where he died on 7 March 1984.
