Henry Watters (June 1, 1853 – May 10, 1924) was mayor of the city of Ottawa in 1924.
He was a founding member of the Canadian Pharmaceutical Association.
When a new city pool, now known as the Champagne Bath, was officially dedicated in May 1924, Watters was supposed to officiate, but died of a heart attack on the way to the ceremony.
So, Napoléon Champagne, then the city comptroller, dedicated the pool a few days later.
Champagne assumed the role of mayor for the remainder of the year.
