What is the name of Edinburgh's main New Year's Eve street party and concert celebration?

The name of Edinburgh's main New Year's Eve street party and concert celebration is Edinburgh's Hogmanay.

Edinburgh's Hogmanay is a major annual festival built around Scotland's New Year celebrations. Its best-known events have included a large street party in the city centre, concerts, torchlight processions, and fireworks near Edinburgh Castle. The exact programme and capacity can change between years.

The festival became especially prominent in its modern organized form during the late twentieth century. It combines older Scottish customs with ticketed concerts and large public events designed for visitors and residents. It should not be confused with Burns Night, which celebrates Robert Burns on January 25, or with the Royal Edinburgh Military Tattoo, a separate summer event.
