Valentin Rose (8 January, 1829 – 25 December, 1916) was a German classicist and textual critic.

In 1855, he took a post at the Royal Library at Berlin, where he remained until his retirement in 1905.

Under his leadership, the library's Manuscript Department (which he headed from 1886), gained a leading international reputation.

He published catalogs of the collection between 1893 and 1905, and among the important discoveries made were texts in the history of medicine and in horticulture.

The third revised edition was published at Leipzig in 1886 with the title Aristotelis Qui Ferebantur Librorum Fragmenta.
