Clement Schrader (November 1820 at Itzum, in Hanover, Germany – 23 February 1875 at Poitiers, France) was a German Jesuit theologian.
On his refusal to take the oath of fidelity to the Constitution of 1867 he was, not long after the council had been prorogued, deprived of his professorship by the Austrian Government.
The remainder of his life was devoted to the teaching of theology at the University of Poitiers, where he succumbed to an attack of pneumonia.
Chief among these are: He assisted Carlo Passaglia in several of his works, notably in the latter's treatise on the Immaculate Conception.
He was also actively engaged in the conduct of a periodical published at Vienna (1864–67), and entitled Der Papst und die modernen Ideen.
