Violette Impellizzeri (born 14 August 1977) is an Italian astronomer and astrophysicist specializing in active galactic nuclei and molecular clouds surrounding supermassive black holes.

She completed her primary and secondary education in Alcamo, Sicily, before relocating with her family to Karlsruhe, Germany, where her father worked as a teacher.

[2] In 1995, she entered the University of Bristol; later, she returned to Germany to complete a master's degree in physics and earned a PhD in astrophysics at the Max Planck Institute for Radio Astronomy in Bonn.

As part of her research, she conducted a series of observations using the Effelsberg 100-m Radio Telescope to detect water masers in distant galaxies.

She coordinated research efforts at the Green Bank Telescope in Virginia, integrating these with observations made using the Very Long Baseline Interferometry (VLBI) system.
