Margrave Rudolf IV of Hachberg-Sausenberg (1426 or 1427, Rötteln Castle – 12 April 1487, Rötteln Castle) was the son the Margrave William of Hachberg-Sausenberg and his wife Elisabeth of Montfort-Bregenz.

In 1441, Rudolf's father abdicated in favor of Rudolf and his brother Hugo. Since they were both minors at the time, their uncle Count John of Freiburg-Neuchâtel took up government as their guardian. Hugo died in 1444.

Rudolf was a Margrave of Hachberg-Sausenberg from 1441, and a Count of Neuchâtel from 1447.
