Lucius Mummius was a Roman statesman and general. He was consul in the year 146 BC along with Gnaeus Cornelius Lentulus.

Novus homo or homo novus was the term in ancient Rome for a man who was the first in his family to serve in the Roman Senate or, more specifically, to be elected as consul. When a man entered public life on an unprecedented scale for a high communal office, then the term used was novus civis or "new citizen".
