Ruaidhrí mac Raghnaill (died 1247?) was a leading figure in the Kingdom of the Isles and a member of Clann Somhairle. He was a son of Raghnall mac Somhairle, and was the eponymous ancestor of Clann Ruaidhrí. Ruaidhrí may have become the principal member of Clann Somhairle following the annihilation of Aonghus mac Somhairle in 1210. At about this time, Ruaidhrí seems to have overseen a marital alliance with the reigning representative of the Crovan dynasty, Rǫgnvaldr Guðrøðarson, King of the Isles, and to have contributed to a reunification of the Kingdom of the Isles between Clann Somhairle and the Crovan dynasty.

In the first third of thirteenth century, the Scottish Crown faced a series of uprisings from the Meic Uilleim, a discontented branch of the Scottish royal family. Ruaidhrí is recorded to have campaigned with Thomas fitz Roland, Earl of Atholl against the Irish in the second decade of the century. One possibility is that these maritime attacks were conducted in the context of suppressing Irish supporters of Scottish malcontents. In 1221/1222, Alexander II, King of Scotland oversaw a series of invasions into Argyll in which Scottish royal authority penetrated into Kintyre. As a result, Ruaidhrí appears to have been ejected from the peninsula and replaced by his younger brother, Domhnall. Whilst Alexander's campaign appears to have been directed at Ruaidhrí, the precise reasons behind it are uncertain. On one hand, the threat of a unified Kingdom of the Isles may have triggered the invasion. On the other hand, if Ruaidhrí had indeed supported the Meic Uilleim, such support to Alexander's rivals could account for royal retaliation directed at Ruaidhrí.

According to several mediaeval chronicles, a certain Roderick took part in the last Meic Uilleim revolt against Alexander. One possibility is that Ruaidhrí and this Roderick are identical. If correct, Ruaidhrí's alliance with the Meic Uilleim may have originated as a consequence of his expulsion from Kintyre by the Scottish Crown. Whilst Ruaidhrí's later descendants certainly held power in the Hebrides and Garmoran, it is uncertain how and when these territories passed into their possession. In 1230, following Scottish interference in the Isles, Hákon Hákonarson, King of Norway sent Óspakr-Hákon to restore authority in the region as King of the Isles. The fact that Ruaidhrí is not recorded in the subsequent Norwegian campaign could be evidence that he had occupied himself in supporting the near-concurrent Meic Uilleim rebellion, or that he resented the prospect of Óspakr-Hákon's overlordship.
