Edouard Silas (22 August 1827 – 8 February 1909) who was born in Amsterdam and died in London, was a Dutch composer and organist.
He studied in Paris with Friedrich Kalkbrenner, François Benoist and Jacques Fromental Halévy.
Silas was organist at the Catholic Chapel of Kingston upon Thames and Professor of Harmony at the Guildhall School of Music.
He composed a Mass for four voices and organ for which he won a Belgian competition for sacred music in 1866.
In his Musical Times obituary, he was remembered as "a character" often seen at the British Museum: "the little man with remarkable features and wearing a red fez".
