Arnold (or Arnoud) van Isenburg (died in April or June 1197) was Bishop of Utrecht from 1196 to 1197.
Arnold descended from the German House of Isenburg and had been provost in Deventer since 1176.
After Bishop Baldwin II van Holland died, Arnold was pushed forward by the count of Guelders.
However, Dirk VII, Count of Holland wanted his uncle, Dirk of Holland as bishop of Utrecht, and he was supported by Henry VI, Holy Roman Emperor.
Both candidates travelled to Rome, where Arnold was consecrated by Pope Celestine III as bishop of Utrecht.
