Dosa ben Harkinas (Hebrew: רבי דוסא בן הרכינס) was of the first generation of the Jewish Tanna sages, proceeding from the era of the Zugot. Contemporary to Yochanan ben Zakai, he was active during the era of the Second Temple of Jerusalem, and lived to a ripe old age, even after the destruction of the Second Temple. His best known saying is cited in Pirkei Avot:
"Sleeping in the morning and drinking wine in the afternoon, the conversation of the children, and sitting in the churchs of amme ha'ares
, can remove a man from this world".
