Isambert is Germanic in Origin.

Isambert is a French form of a medieval Germanic name related to Isambard, built from isarn/isan (“iron”) and berht (“bright, famous”). The final -bert reflects the widespread -bert element in continental Germanic given names. As a meaning, it conveys “iron‑bright,” “shining like iron,” or by extension “steadfast and renowned.”

The name circulated in Normandy and northern France from the 10th–12th centuries and crossed into England with the Normans, where spellings such as Isembard and Isambard appear in charters. It survives more commonly as a French surname (compare the jurist François-André Isambert) derived from the old given name, while the English form was revived in the 19th century by engineer Isambard Kingdom Brunel. Documented variants include Isambard, Isambart, Isembert, Isenbert, and the Latin Isambertus/Isembertus; Italian/Spanish Isambardo also occurs. Today Isambert is rare as a first name, retaining a distinctly medieval, Franco-Norman character.
