What was the name of Guy Lombardo's orchestra, famous for broadcasting New Year's Eve music from New York?

Guy Lombardo's New Year's Eve orchestra was called the Royal Canadians.

Lombardo and his brothers formed the band in Canada in the early twentieth century, and it became known for a polished dance-band style sometimes described as “the sweetest music this side of heaven.” The group broadcast its New Year's Eve performances for decades, helping establish the association between midnight celebrations and live popular music on radio and television.

The broadcasts were especially linked with the Roosevelt Hotel in New York City, where the orchestra performed for many years. Later, the Times Square Ball drop became the dominant visual symbol of the American countdown, but Lombardo's music remained a major part of the holiday tradition for generations.

The Royal Canadians continued after Lombardo's death in 1977 under other leadership, although the original era is the one most often remembered. The name refers to the orchestra, not to a Canadian military unit or a royal ceremony.
