Henri Paul Royer (22 January 1869 – 31 October 1938) was a French painter, remembered especially for his genre works from Brittany.

He was the son of Jules Royer (1845–1900), the founder of one of Nancy's most significant lithographic printing establishments located on Rue de la Salpêtrière.

These early successes prompted his parents and teachers to encourage a study trip to Holland with Friant, who subsequently left a lasting impact on Royer.

In 1890, he continued his studies at the Académie Julian under the guidance of Jules Joseph Lefebvre and François Flameng.

Among his many students were Georgina and Lucilio de Albuquerque, Fréderic Fiebig, Jacques Majorelle, Thérèse Geraldy and Émile Louis Picault.
