Václav Vačkář (12 August 1881 – 4 February 1954) was a Czech composer and conductor of the late romantic era.

After his time in Poland Váckář began to play and conduct in various local orchestras including the Czech Philharmonic.

[1] In 1952 he wrote the book Instrumentace symfonického orchestru a hudby dechové ("Instrumentation for the Symphony Orchestra and Wind Music") with his aforementioned son Dalibor Cyril Vačkář which is still taught in Czech conservatories.

[2] Vaćkář's predecessor Bedřich Smetana innovated the Czech nationalistic style.

Another significant influence on Vačkář was Antonín Dvořák who was also a champion of Czech nationalism.
