Bibia Mudalal () was a 19th-century Mandaean priest and scribe. She was perhaps the last Mandaean female priest. She is known as the wife of Ram Zihrun.
Bibia Mudalal's mother was Hawa Simat, and her father was Adam Yuhana, son of Sam. Her father came from the Kamisia and Rià ¡ Draz families. She was a scribe who copied the Ginza Rabba and also a priest who was likely initiated before the 1831 cholera epidemic that killed all of the other Mandaean priests.
Bibia Mudalal was the grandmother of Sheikh Negm (or Sheikh Nejm; born 1892 in Huwaiza, Iran), who copied many manuscripts for E. S. Drower.
