The shawm was a Renaissance musical instrument of the woodwind family, made in Europe from the late 13th century until the 17th century. It was ancestral to the modern oboe.

It had a long bore which started straight but widened into a conical end, and had a double reed. It produced a loud shrill tone, and was used by military bands during the Crusades, as well as in ordinary life for dancing.

The oboe developed from the shawm in the mid-17th century when the French musicians Jean Hotteterre and Michel Danican Philidor modified it, producing an instrument with a narrower bore and a reed which is held by the player's lips near the end.
