George "Sjoppie" Fles (Russian: Георгий Людвигович Флэс, romanized: Georgiy Lyudvigovich Fles; 1908–1939) was a Dutch translator with a strong communist conviction.
George was born in 1908 in Amsterdam, as the youngest son of Louis Fles and Celine van Straaten.
He spent time in France and in the United Kingdom, where he married Pearl Rimel.
After George's death, Pearl Rimel and their son Michael John Fles emigrated to the United States and settled in Los Angeles.
At the request of family members, the Soviet Union later "rehabilitated" George Fles.
