Emma of Altdorf, also known as Hemma (c. 803 – 31 January 876), a member of the Elder House of Welf, was the wife of King Louis the German, and thereby Queen consort of East Francia from 843 until her death.

Her father was Welf I (d. 825), Count of Altorf in Alamannia; her mother was Hedwig (Heilwig; c. 775 – after 833), a daughter of the Saxon count Isambart. Emma's elder sister was Judith (sometimes called of Bavaria), who in February 819 married the Carolingian emperor Louis the Pious, and thereby became Queen consort of the Franks and Holy Roman Empress. The marriage marked a crucial step forward in the rise of the Welf dynasty.

In 827, probably at the instigation of Judith, Emma married Louis the German, the youngest son of Emperor Louis the Pious from his first marriage with Ermengarde of Hesbaye, and stepson of Emma's sister Judith. The wedding cereminy possibly took place in Regensburg, Bavaria, where since 817 Louis the German was to rule as a King of Bavaria subordinate to his father; Emma was thus Queen consort of Bavaria. She was given in 833, by her husband Louis, Obermünster Abbey in Regensburg.

Emperor Louis died in 840. After severe innerdynastic struggles, the Carolingian Empire eventually was divided according to the Treaty of Verdun in 843. The Kingdom of Bavaria was merged in Louis the German's Kingdom of East Francia (the predecessor of the Kingdom of Germany), and his wife Emma became first East Frankish queen.
