What is the name of the New Year's Eve street celebration held in Edinburgh on December 30 and 31?

The New Year's Eve street celebration held in Edinburgh on December 30 and 31 is Edinburgh's Hogmanay.

Hogmanay is the Scottish name for New Year's Eve, and Edinburgh's modern festival developed into a large program of concerts, a torchlight procession, street events, and a midnight fireworks display. The principal street celebration takes place along Princes Street, with Edinburgh Castle forming a dramatic backdrop. The festival attracts visitors from around the world, although exact events and crowd arrangements can change from year to year.

The term Hogmanay has uncertain etymology. Proposed explanations connect it with French, Norse, Gaelic, and Scots usage, but no single origin is universally accepted. Scotland's New Year customs also include first-footing, in which the first person to enter a home after midnight is traditionally associated with the household's luck for the coming year.

Hogmanay is broader than one song or one countdown. “Auld Lang Syne” is commonly sung in Scotland and internationally at midnight, but it is not the name of Edinburgh's festival. The festival's official branding and the city's own event listings use Edinburgh's Hogmanay.
