Johann Wiards Albert Schröder (4 April 1925, Norden, Lower Saxony – 3 January 2007) was a German mathematician.
Schröder studied mathematics and physics at Leibniz University Hannover and the University of Göttingen. In 1952 at Leibniz University Hannover he received his Promotion (Ph.D.) under Lothar Collatz for his thesis "Fehlerabschätzungen zur Störungsrechnung bei linearen Eigenwertproblemen".
In 1955 Schröder received his Habilitation. From 1955 to 1957 he taught at the Braunschweig University of Technology and from 1957 to 1963 at the University of Hamburg, where from 1961 to 1963 he was an adjunct professor.

In 1966 at the International Congress of Mathematicians in Moscow he was a Plenary Speaker with his talk "Ungleichungen und Fehlerabschätzungen" (Inequalities and error estimates).
He died as a result of an accident and was buried in the Bensberg cemetery.
