Oldřich Duras (born Důras; 30 October 1882 – 5 January 1957) was a Czech chess master.

After World War I, he got married, which is considered a possible reason for the early end of his active career.

[1][2] Duras was among the leading chess masters of the early 20th century, even though his career was short.

He lost the one game he played with Emanuel Lasker, had a draw and a loss against José Raúl Capablanca, and heavy minus scores against Akiba Rubinstein, Ossip Bernstein and Milan Vidmar and was one game behind with Frank Marshall (+7-8=5).

[1] In the poll for the best Czechoslovak player of the century, Oldřich Duras came in fourth place (after Richard Réti, Vlastimil Hort and Salo Flohr).
