Ronalds Žagars (born 1950 in Ventspils) is a former Latvian football goalkeeper who played for Zvejnieks Liepāja and FK Daugava Rīga.
He first played in Liepāja but was offered to join Daugava Rīga in the first Soviet league.
Over the first two seasons with Daugava he played only 12 matches and had to return to Zvejnieks Liepāja.
[1] In 1974, he was invited to Daugava again for the best season of his career – he played almost half of the team's matches (23) and had nearly the same amount of time in goal as his more famous colleague Laimonis Laizāns.
In 1977 at the age of 27 Žagars left Daugava and joined Enerģija Rīga with which he won the Latvian league in 1977.
