Alexandru A. Bădărău (April 9, 1859–March 27, 1927) was a Romanian politician, academic, and journalist.

Bădărău continued his education at the University of Paris, where he obtained a law degree, also earning a diploma from the École Libre des Sciences Politiques.

[1] After returning home in 1885, he became a French teacher at two schools in Iași as well as a psychology professor within the local university's literature faculty.

One of his priorities was to create a public water-supply system to bring water from the Prut River to the city; he argued at length with his predecessor, Nicolae Gane, who favored bringing water from Timișești.

After he left office, the Timișești variant was chosen, and Bădărău went there in April 1907 for the start of the works.
