Nicholas Grigoryevich Sergeyev (Russian: Никола́й Григорьевич Серге́ев, variously written in the Latin alphabet as Nicholas or Nikolai Sergeev, Sergueev or Sergueeff etc.) was a Russian ballet dancer, choreographer and teacher, and regisseur of the Imperial Ballet at the Maryinsky Theatre, St Petersburg. He fled Russia in 1919 and spent the rest of his life in the West, producing ballets for many of the leading western companies of the time. He is remembered for preserving what is now called the Sergeyev Collection for future generations.
