Estrella Miyakawa was a Human female who lived during the 24th century. A native of Mexico on Earth, Miyakawa was a member of the Federation Starfleet.

At Starfleet Academy, Miyakawa was a classmate of future USS Enterprise-D commanding officer, Jean-Luc Picard. While at the academy Picard tutored her on some of her courses in exchange for her teaching him Spanish. Neither effort was successful at the time.

By 2368, Miyakawa was the commanding officer of Starbase 193. As the base was on the frontier, she was the sole Starfleet officer on the base, which was crewed by civilian technicians. When the Devil's Heart resurfaced, the base was destroyed by Romulans seeking to reclaim the Heart. Miyakawa survived the destruction and led the efforts to rebuild the base.
