Friedrich Albert von Zenker (13 March 1825 – 13 June 1898) was a German pathologist and physician, celebrated for his discovery of trichinosis.

While in Leipzig, he worked for a while as an assistant to Justus Radius at the St. Georg Hospital.

Three years afterwards he assumed with Hugo Wilhelm von Ziemssen the editorship of the "Deutsches Archiv für klinische Medizin".

Zenker's diverticulum, a false pathological diverticulum of the posterior pharyngeal wall, through the thyropharyngeus and cricopharyngeus parts of the inferior constrictor muscle, is named after him.

In that year he published "Ueber die Trichinenkrankheit des Menschen" (in volume xviii of VirchowsArchiv).
