Frederick II of Dießen (also known as Frederick I of Regensburg; 1005 – 1075) was a German nobleman. He is documented as bailiff (Vogt) of the Regensburg cathedral chapter in 1035. He is one of the earliest known ancestors of the Counts of Andechs.
His father was Count Frederick of Dießen (d. c. 1030), a relative of the legendary Bavarian count Rasso (d. 954), who administered the area around Dießen and Haching. His mother was Hemma, a daughter of Duke Conrad I of Swabia.
