Arnold House School is a preparatory school for boys in the St John's Wood district of Westminster, Greater London. It consists of a Junior School (Years 1-4) and Senior School (Years 5-8).
Arnold House School was founded in 1905 by Miss Hanson with nine pupils. Hanson opened the school with the intention of showing that a headmistress was equally capable of preparing boys for public schools. By the time she stepped down as Headmistress, the school was flourishing. It became a charitable trust in 1969.
In celebration of the school's centenary in 2005, it applied for and was granted a Coat of Arms by the College of Arms. It features the passage from which the school motto is derived:
"Conquer we shall, but first we must contend,
’Tis not the strife that crowns us, but the end."
— Robert Herrick
