Richeza of Berg (Czech: Richenza z Bergu; c. 1095 – 27 September 1125) was Duchess of Bohemia from 1111 to 1117 and again from 1120 until 1125, by her marriage with the Přemyslid duke Vladislav I.
The ducal couple founded the Benedictine monastery of Kladruby in 1115; Richeza also made several donations to Zwiefalten Abbey in her Swabian homelands.
Through the intercession of his wife, in 1125 the dying Duke Vladislav I chose his cousin Prince Otto II the Black as his successor.
Only the intervention of his mother, the aged queen dowager Świętosława (Svatava), changed his mind and Vladislav reconciled with his younger brother Soběslav.
Her eldest son Vladislav II succeeded to the Prague throne after Duke Soběslav's death in 1140.
