Erin Constantino was a female Human from Deneva in the 24th century.

As of 2381, she was an ensign in Starfleet, assigned to the USS Aventine as beta shift conn officer. She was on duty when the runabout USS Seine blew out the shuttlebay and made an escape; she plotted the intercept course and followed the ship through the subspace tunnel into the Azure Nebula, ending up at the former site of Erigol. (ST - Destiny novel: Gods of Night)

After answering a distress call from the USS Enterprise-E at the Azure Nebula, the Aventine scouted several additional subspace tunnels from the nebula. Constantino was on duty when the ship passed through one of those tunnels to end up in the intergalactic void. (ST - Destiny novel: Mere Mortals)

Constantino lost her entire family on Deneva during the Borg Invasion of 2381, including her parents, grandparents, husband and daughter.

Constantino was also a guitarist, and performed in an impromptu concert with Professor Sonek Pran during his time aboard the Aventine in early 2381. (ST novel: A Singular Destiny)
