Vladimír von Szmurlo (pronounced "shmurlo"; 1865–1931) was a Russian Esperantist and railway engineer.

In 1910 he founded the Esperanto association La Riga Stelo and became its first president.

He wrote ANA (Alfabeta Nomaro-Adresaro), also known as Ariadna fadeno ("Ariadne's Thread"), a first attempt at an Esperanto encyclopedia, from 1914 to 1917.

In his last years, he was interested principally in the various systems and institutions of the Lingvo Internacia (Esperanto, as it is most commonly known today).

In 1920 he created a derivative auxiliary language called Arlingo, based on Esperanto, which was never published.
