Johannes Cocceius (also Coccejus; 9 August 1603 – 5 November 1669) was a Dutch theologian born in Bremen.

After studying at Hamburg and the University of Franeker, where Sixtinus Amama was one of his teachers, he became in 1630 professor of biblical philology at the Gymnasium illustre in his native town.

[1] His major work was his Lexicon et commentarius sermonis hebraici et chaldaici (Leiden, 1669), which has been frequently republished.

This Cocceian procedure, known today as "biblical theology", was set against the analytical doctrine-by-doctrine approach of his contemporaries in Holland—most famously, Voetius.

As an exponent of federal theology he was tacitly influenced by his teachers in Bremen, Matthias Martinius and Ludwig Crocius.
