Clovis la Britannia is a minor character in the anime series Code Geass: Lelouch Of The Rebellion. He is voiced by Nobuo Tobita in the original Japanese and by Sam Riegel in the English dub.

Clovis is the Third Prince of the Holy Britannian Empire and half-brother of the series' protagonist Lelouch vi Britannia. He appears in the first three episodes of the series, fulfilling the role of viceroy of Area 11 (Japan after Britannia's conquest). Shortly after Lelouch gains the power of Geass, he makes contact with a Japanese resistance cell and organises their actions against Britannia. Clovis frantically tries to direct his troops against the terrorists, but in the end all his forces in Shinjuku Ghetto are overwhelmed by Lelouch's superior strategy. Lelouch infiltrates Clovis's operations center and holds him at gunpoint, demanding that the viceroy order his remaining forces to pull out of Shinjuku. With the order given, Lelouch then uses the Geass to force Clovis to reveal all he knows regarding the murder of Lelouch's mother Marianne. It turns out Clovis doesn't know much and Lelouch decides that he is no longer useful and pulls the trigger on his half-brother as Clovis begs for mercy. And so, Clovis becomes the first casualty on Lelouch's mission of revenge against Britannia.
