Henry V (German: Heinrich V.; 1081 or 1086 (probably on 11 August) – 23 May 1125, in Utrecht), was King of Germany (from 1099 to 1125) and Holy Roman Emperor (from 1111 to 1125), as the fourth and last ruler of the Salian dynasty. He was made co-ruler by his father, Henry IV, in 1098.

In Emperor Henry IV's conflicts with the imperial princes and the struggle against the reform papacy during the Investiture Controversy, young Henry V allied himself with the opponents of his father. He forced Henry IV to abdicate on 31 December 1105 and ruled for five years in compliance with the imperial princes. He tried, unsuccessfully, to withdraw the regalia from the bishops and in order to at least preserve the previous right to invest he captured Pope Paschal II and forced him to perform his imperial coronation in 1111. Once crowned emperor, Henry departed from joint rule with the princes and resorted to earlier Salian autocratic rule. After he had failed to increase control over the church, the princes in Saxony and on the Middle and Lower Rhine, in 1121 the imperial princes forced Henry V to consent with the papacy. He surrendered to the demands of the second generation of Gregorian reformers, and in 1122 he and Pope Callixtus II ended the Investiture Controversy in the Concordat of Worms.
