Avigdor Dagan (Hebrew: אביגדור דגן; born Viktor Fischl; 30 June 1912 – 28 May 2006) was a Czech-Israeli writer, playwright, literary translator, and diplomat.

After graduating from the Charles University in Prague, he entered the diplomatic service.

In 1939 he emigrated to the United Kingdom to escape the Nazis, where he became an associate to Jan Masaryk.

After a long break, publication resumed in his home country, and his works received broader recognition.

In his lifelong literary career, he started out as a poet, then later became known as a writer of collections of short stories and novels.
