Rhineland Bastard () was a derogatory term used in Nazi Germany to describe Afro-Germans, believed fathered by French Army personnel of African descent who were stationed in the Rhineland during its occupation by France after World War I. There is evidence that other Afro-Germans, born from unions between German men and African women in former German colonies in Africa, were also referred to as Rheinlandbastarde.
After 1933, under Nazi racial theories, Afro-Germans deemed to be Rheinlandbastarde were persecuted. They were rounded up in a campaign of compulsory sterilization.

History
The term "Rhineland Bastard" can be traced to 1919, just after World War I, when Entente troops, most of them French, occupied the Rhineland. The British historian Richard J. Evans suggests the number of mixed-race children among them was not more than five or six hundred.

All World War I belligerents with colonial possessions went to great lengths to recruit soldiers from their colonies. Germany was the only one of the Central Powers with substantial overseas possessions; it used numerous non-white troops to defend its colonies. Regardless of German attitudes toward the indigenous inhabitants of German colonies, Germany's lack of control of the sea lanes would have made it nearly impossible for the German Army to bring any substantial number of colonial troops to European battlefields. Notwithstanding the exact circumstances, most Germans quickly came to view non-white Allied troops with disdain and were contemptuous of the Allies' willingness to use these troops in Europe.

Germans across the political spectrum regarded the occupation as a national disgrace. Many considered all forms of collaboration and fraternization with the occupiers as immoral (if not illegal) treason. From the spring of 1920 onward, German newspapers frequently ran hysterical stories about the alleged "Black Horror on the Rhine", accusing Senegalese soldiers of routinely gang-raping thousands of German women and girls on a daily basis. In the popular 1921 novel Die Schwarze Schmach: Der Roman des geschändeten Deutschlands (The Black Shame A Novel of Disgraced Germany) by Guido Kreutzer, he wrote that all mixed race children born in the Rhineland are born "physically and morally degenerate" and are not German at all. Kreutzer also declared that the mothers of these children ceased to be German the moment they had sex with non-white men, and they could never join the Volksgemeinschaft.
As Germans considered the occupation to be carried out by "B-grade" troops (a notion that was drawn from colonial and racial stereotypes), their humiliation was heightened, increasing hostility toward the women and children in these unions. In May 1920 the foreign minister of the new German government lodged a protest to his French counterpart stating that "we will accept the inferior discipline amongst your white troops if you will only rid us as fast as possible of this black plague".
In the Rhineland itself, local opinion of the troops was very different. The soldiers were described as "courteous and often popular", possibly because French colonial soldiers harbored less ill-will towards Germans than war-weary French occupiers.
In his book Mein Kampf, Adolf Hitler described children resulting from any kind of relationship to African occupation soldiers as a contamination of the white race "by Negro blood on the Rhine in the heart of Europe." He thought that "Jews were responsible for bringing Negroes into the Rhineland, with the ultimate idea of bastardizing the white race which they hate and thus lowering its cultural and political level so that the Jew might dominate." He also implied that this was a plot on the part of the French, since the population of France was being increasingly "negrified".
