Jonas Marcus von Königswarter (10 August 1807 – 23 December 1871) was a distinguished Austrian Jewish financier and pioneer in the railway industry, belonging to the notable Königswarter lineage.

Originating from Frankfurt in the post-Napoleonic era, he eventually made Vienna his home and took charge of the banking firm established by his uncle, Hermann Königswarter. During his tenure, the institution rose to become one of Austria’s foremost financial entities. Königswarter held influential positions such as examiner in 1838 and director by 1850 at the Oesterreichische Nationalbank. His board memberships extended to the Oesterreichische Creditgesellschaft, Emperor Ferdinand Northern Railway, Süd-Norddeutsche Verbindungsbahn, and Böhmische Westbahn—the latter of which he led as president for several years. Moreover, he was part of the advisory committee for the Wiener Börse and served as president of Vienna’s Jewish community.

In acknowledgment of his achievements, Königswarter was awarded the third-class Order of the Iron Crown, received hereditary knighthood, and was later promoted to baron with a second-class distinction in 1870. Above all honors, he cherished the personal regard bestowed by Emperor Francis Joseph I.

As a conservative figurehead within Vienna’s Jewish population—holding the presidency in 1868 and again in 1871—he actively endorsed the Alliance Israélite Universelle. Upon his passing, Königswarter was interred beside Gustav von Epstein, another patron of the Ringstrasse, at the Wahring Jewish Cemetery.
