Conrad I of Brno (Czech: Konrád I. Brněnský) (died 6 September 1092) was the duke of Bohemia for eight months in 1092. He was the brother and successor of Vratislaus II (died 14 January 1092) as the third son of Bretislaus I and Judith of Schweinfurt. He did not succeed as king, because his brother had only been lifted to the royal dignity ad personam by the Emperor Henry IV and that title was therefore not hereditary.
Before he became duke of Bohemia, he had long ruled over Moravia, as junior sons typically did, as duke of Brno and Znojmo (since 1054).
By his marriage to Wirpirk of Tengling, he had two children:
- Oldřich (or Ulrich), prince of Brno from 1092 to 1097 and from 1100 to his death on 11 November 1115
- Luitpold, prince of Znojmo from 1092 to 1097 and from 1100 to his death on 15 March 1113
He was succeeded as duke by his nephew Bretislaus.
