Pirka Riyannis, née Saroyn, was a female Trill who lived during the late 24th century. She was the fourth host of the Riyannis symbiont. Pirka Riyannis was a folk musician who played the bass fife, and was reasonably well-known on the Trill planetary internet despite primarily playing for her own enjoyment. She had several daughters. Pirka was declared clinically dead after an aircar crash in the 2390s, and the symbiont was transferred to Birail Izer.
