François-Etienne Calla (* 1760 ; † 1835/36) was a French mechanic.

He was a student of Jacques de Vaucanson . In 1788 he founded a factory for spinning machines in Paris in Rue du Faubourg St. Denis No. 9.

In 1800 he built a steam engine for Robert Fulton , which should work at 32 atmospheres and in which steam and water were separated. However, it was abandoned again. Around 1802 he and the brothers Jacques-Constantin and Augustin-Charles Périer Fulton helped build the Nautilus .

In 1820 he added his own foundry to the workshop. In the same year he donated a fountain to the Rue du Faubourg-Piossonnière.

In 1834 his son, Cristophe-François Calla (* 1802; † February 24, 1884 in Nice) took over the management of the factory, improved iron casting and achieved great skill in art casting. He later turned to machine tool manufacturing and built the first French locomotive in 1852.
