Musa Haji Ismail Galal (Somali: Muuse Xaaji Ismaaciil Galaal, Arabic: موسى الحاج اسماعيل جلال) (1917–1980) was a Somali writer, scholar, linguist, historian and polymath.

In the 1950s, Galal introduced a more radical alteration of the Arabic script to represent the Afro-Asiatic Somali language.

Lewis (1958) considers this to be the most accurate Arabic script to have been devised for the Somali language.

Later, he took part in the development of Somali Latin alphabet, along with B. W. Andrzejewski and Shire Jama Ahmed.

[1][4] A prolific writer, Galal was also among the foremost authorities on the Somali astrological, meteorological and calendrical systems.
