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.
Rudolf married Margaret of Vienne. She brought Sainte Croix Castle and other property in Burgundy into the marriage. They had at least two children: a son, Philip and a daughter. Catherine.
Rudolf IV expanded Badenweiler Castle and Rötteln Castle. To the latter, he added the lower gate in the outer bailey. Between 1479 and 1482, he rebuilt the City Church in Schopfheim, which had burned down. There are traces of his construction activities in the monastery church at Weitenau and in the churches of Rötteln and Egringen.
On 8 September 1444, Count John of Freiburg-Neuchâtel gave the Badenweiler district, including Badenweiler Castle to his nephews Rudolf IV and Hugo. The districts of Badenweiler, Rötteln and Hachberg-Sausenberg then formed an almost contiguous area Markgräflerland, north of Basel and south of Freiburg.
Count John of Freiburg-Neuchâtel and his wife Marie of Chalon had six children, but they all died in childhood.
