Baba Deep Singh Shaheed (26th January 1682 - 13th November 1757), is one of the most honoured martyrs in Sikh history. Baba Deep Singh was the founder and leader of the famous "Shaheedan Di Misl" among the 12 misls.

Baba Deep Singh was the first head of Damdami Taksal (Damdama school of learning) a 300 years old religious school of the Sikhs which was founded by Sri Guru Gobind Singh Ji. Tall and strong, Baba Deep Singh Ji was an exceptionally brave Sikh.

A bold and fearless saint-soldier Baba Deep Singh was ever ready to risk his life for the Panth. Baba Deep Singh was born on January 26, 1682 (some records register this as January 20) and died fighting at Amritsar in November 1757 when he was about 75 years old. From about 12 years of age, he grew up around the tenth Guru, Guru Gobind Singh.

Baba Deep Singh spent most of his life as a custodian of the Panth (Sikh community). He and Banda Singh Bahadur are recognised as the most honoured martyrs of the Panth who, together set a unique and amazing example for the community to follow for many generations.

Not only was Baba Deep Singh a brave and fearless soldier but a very intelligent scholar who had mastered several languages.

From the time when Guru Gobind Singh came to Damdama Sahib, Baba Deep Singh was responsible for the distribution of the Guru Granth Sahib to other parts of the world and was the "head granthi" (head priest) of Damdama Sahib in Bathinda.
