Bi Bi Monajemeh Nishaburi (Persian: بی بی منجمه نیشابور) also known as Monajemeh Nishaburi or Bichai Munachchima[1] (1203 – 1280) was a Persian-Tajik poet, mathematician and astronomer.

Monajemeh learned about astronomy from her father; their house was used as a meeting place for scholars, intellectuals and philosophers, which enabled Monajemeh to learn about mathematics and astronomy at a young age.

[3] Contemporary commentaries refer to Monajemeh as a virtuous woman, with a deep knowledge of astrology and making calendars.

[4] Monajemeh's profession as astrologer can be deduced from her title monajjema,[5] worked as an astronomer and a consultant for Shah Jalal ad-Din Mingburnu (until 1247) and Shah Kayqubad I, both of whom believed in the use of astrology when devising military tactics.

[2] Monajemeh married Majd ad-Din Mohammad, an official in the court of Jalal ad-Din Mingburnu,[3] who had previously been an official under Šams-al-Dīn Moḥammad, grandfather of the Persian statesman Shams al-din Muhammad ibn Muhammad Juvayni.
