Franz Philip Kaulen (born 20 March 1827, at Düsseldorf; died at Bonn, 11 July 1907) was a German Catholic scriptural scholar.
For several years he was engaged on the mission in various stations of the Diocese of Cologne, until in 1859 he was appointed lecturer at the Konvikt or theological school at Bonn.
In 1890 he was raised to the dignity of a domestic prelate by Pope Leo XIII; in 1900 he received the grand cross of the Order of the Knights of the Holy Sepulchre, and in 1903 he was made a member of the Biblical Commission.
A second edition soon appeared necessary: in 1877 the editorship was entrusted to Joseph Hergenröther, then professor in Würzburg, but, at the elevation of the latter to the cardinalate in 1879, was finally given to Kaulen, who presided over the work until it was completed.
Kaulen was helped by Hermann Streber, by Albert Maria Weiss, O.P., who prepared the catalogue of subjects, and by a large number of learned contributors, the list of whom is given at the end of the last volume.
