Shiraz is the name of a grape variety used to make a popular style of red wine, either on its own or blended with others. It is grown in many wine producing regions around the world.

It is generally known as Syrah in France, though some argue that Syrah and Shiraz have diverged sufficiently to be considered separate varieties. In other countries where it is cultivated, usage differs.

It has sometimes been thought that the name of the grape Shiraz was taken directly from that of the city of Shiraz, Iran. More likely is that the name of the grape is a modification of "Scyras," one of a number of synonyms for Syrah in the Rhône Valley, where it was already established in Roman times and from where it was taken to Australia by James Busby in 1832.

In France Shiraz is the main grape of the Northern Rhône (where it is always called Syrah), associated with classic wines such as Hermitage and Côte-Rôtie. Although its best incarnations will age for decades, it is usually regarded as an early-drinking wine. For this reason it has been widely used as a basic blending grape in the red wines of many countries.

Wines made from Shiraz are quite powerfully flavoured and full-bodied, reminiscent of blackcurrants, with a distinctive "spicy" finish. With time in the bottle these flavours are moderated, and indeed many premium Shiraz-based wines are at their best after some considerable time aged in a cellar.

Though it is usually known as Shiraz in Australia, some winemakers there occasionally sell it as "Syrah" and it is also sometimes called Hermitage. South Africa usually calls it Shiraz. In the USA this grape is grown primarily in California, where it is most commonly called Syrah. Adding some confusion is the fact that it is not uncommon for Shiraz wines to be labelled as "Syrah" when exported to some parts of the world.
