Einar Holbøll (December 20, 1865 – February 23, 1927) was a postmaster and philanthropist from Denmark who conceived the idea of Christmas Seals and was fundamentally involved in their issuance.

They were sold at post offices to raise much needed funds to research and fight tuberculosis, an incurable lung disease that was occurring in alarming proportions in Denmark and other countries around the world, esp among children.

With much public support and with the King's blessing Holbøll was able to have the Danish postal service print Christmas seals and sell them for a penny a piece throughout post offices across Denmark.

Its funding and management was entrusted to the National Association for fight against Tuberculosis, and was also slated for the establishment of various convalescent homes for afflicted children throughout Denmark.

By the time of Holbøll's death, forty-five nations were issuing and using Christmas seals to fight the dreaded disease of tuberculosis.
