Henry Herbert Lyon (April 17, 1879 – November 1, 1917) was an American politician who served on the Los Angeles City Council and in both chambers of the California State Legislature before his death in 1917.

Lyon ran for re-election but lost as only the first nine were elected, with Richmond Plant beating him by 309 votes.

In 1912, he announced himself as a candidate for California State Senate for the 29th district, with Lyon expecting to poll by a large vote.

He won re-election in 1916 without any opposition; that same year, some of his supporters circulated a petition so that he could run for Mayor of Los Angeles.
