Mātā Jīto (1670 – 5 December 1700, Gurmukhi: ਮਾਤਾ ਜੀਤੋ, Shahmukhi: ماتا جیتو), or Ajeet Kaur, was a wife of Guru Gobind Singh.

[1][6] The initial marriage ceremony between Mata Jito and Guru Gobind Singh took place when she was seven years old and he was eleven.

The muklawa, a traditional ceremony marking the completion of the marriage, was held in late 1688, after Mata Jito had reached puberty, following Guru Gobind Singh's return from Paonta Sahib to Anandpur.

According to Bhai Kahn Singh Nabha in the Mahan Kosh, Mata Sahib Devan was present during the creation of Khalsa Panth and participated in making Pahul by adding sugar wafers[9] but the Twarikh Guru Khalsa refutes this claim.

[10] According to Kanwarjit Singh Kang, a fresco that was located in the original Akal Takht depicting a woman appending sugar crystals to Amrit during the Vaisakhi events of 1699 depicts Mata Jito, not Mata Sahib Devan.
