Altun Jan Khatun (died December 1060) was the principal consort of Sultan Tughril I, the founder of the Seljuk Empire, ruling from 1037 to 1063.
[1][2] Tughril Beg is reported to have consulted his chief wife Altun Jan in affairs, Sibt ibn al-Jawzi states that she was a religious woman, much given to charitable works, of good judgement and firm determination.
[3][4] When Tughril Beg went to Hamadan in 1058 to deal with the revolt of Ibrahim Inal, he sent Altun Jan, Anushirwan and al-Kunduri to Baghdad.
Despite the Caliph's objection, Altun Jan went to join her husband at Hamadan, taking the treasury and Seljuk soldiery in Baghdad with her, leaving al-Kanduri.
However, Anushirwan attracted no support, and Altun Jan soon dissociated herself from the plot, all of whose conspirators appear to have been eventually restored to favor without further punishment.
