Ruzbahan ibn Vindadh-Khurshid (Persian: روزبهان بن ونداد خورشید‎‎), better known as Ruzbahan (also spelled as Rezbahan), was a Daylamite military officer who served the Buyid dynasty. A native of Daylam, Ruzbahan began serving the Buyids at an unknown date and quickly rose into high ranks. After constant pressure from king Mu'izz al-Dawla to conquer Batihah, he, along with his two brothers, started a rebellion lasting from 955 to 957. After the end of the rebellion, Ruzbahan was imprisoned and shortly executed.

Ruzbahan was the son of a certain Vindadh-Khurshid, and had two brothers named Asfar and Bullaka. Like his Buyid overlords, Ruzbahan was a Daylamite. However, unlike the Buyids, he probably belonged to a family of noble origin. When the Buyid ruler Mu'izz al-Dawla conquered Iraq in 945, Ruzbahan was appointed as the tax collector of the Sawad. Ruzbahan was originally a low rank officer who served a Buyid officer named Musa Fayadhah. However, under Mu'izz al-Dawla he rapidly rose to higher ranks and became a favourite of Mu'izz al-Dawla.

In 948/949, during negotiations between Mu'izz al-Dawla's and the Sallarid ruler Marzuban's ambassadors, Marzuban was greatly insulted, and became enraged; he tried to avenge himself by marching towards Ray, which was under the control of Mu'izz al-Dawla's brother Rukn al-Dawla. Rukn al-Dawla, however, managed to trick and slow Marzuban down by diplomatic means, while he was receiving aid from Mu'izz al-Dawla, who sent an army under Sebük-Tegin, which also included other officer such as Ruzbahan, Burarish, Ibrahim ibn al-Mutawwaq, 'Ammar "the Mad", and Ahmad ibn Salih Kilabi. However, when the army was close to Dinavar, Burarish, who disliked Sebük-Tegin and refused to obey the orders of the latter, mutinied along with most of the Daylamites in the army, except Ruzbahan and other Daylamite officers. Burarish shortly heavily wounded Sebük-Tegin, who, however, managed to flee from the latter. For unknown reasons, Burarish shortly fled, but was quickly captured by the supporters of Sebük-Tegin. The army of Sebük-Tegin then continued to Ray, and at the same time, reinforcements arrived from Shiraz. Rukn al-Dawla shortly managed to defeat and capture Marzuban.
