Dedi (or Dedo) II (died 1069), called the Younger (Latin: iunior), was the Margrave of the Saxon Ostmark (also called Lower Lusatia) in 1069.
Dedi II was the eldest son of Dedi I of the Saxon Ostmark and his first wife, Oda, daughter of Theitmar of the Saxon Ostmark.
Sometime after 1063, he was given the Sword of Attila by Otto of Nordheim, who had acquired it from Queen Anastasia of Hungary.
[3] Later that same year (before 26 October 1069), Dedi was murdered while relieving himself at night, and thus predeceased his father.
[4] The Sword of Attila was confiscated by the king upon Dedi's death.
