Al-Ajurrumiyah or Jurumiyah or Aajurroom[1](Arabic: الآجُرُّومِيَّة) is a small book on Arabic grammar from the 7th century H/13 AD.

The book Al-Ajurumiyah was compiled by a linguist from Morocco named Abu Abdillah Sidi Muhammad bin Daud Ash-Shanhaji alias Ibnu Ajurrum (d. 1324 AD). The basic formulas for studying classical Arabic are written in rhyming form to make it easier to memorize.

The Jurumiyyah Book contains a collection of nahwu material which covers almost the entire core of nahwu science. This book contains 24 chapters which contain material about important terms in the science of Nahwu such as isim, fi'il and letters.

Al-Ajurumiyah must be mastered by students who want to study the yellow book, because it is impossible to read without studying the Jurumiyah book, a basic guide to the science of nahwu. The next levels after Jurumiyah are Imrithi, Mutamimah, and the highest is Alfiyah
