This documents the records and playoff results of seasons completed by the original-era Ottawa Senators ice hockey club, officially known as the Ottawa Hockey Club from the period of 1883 until 1934. The first reference to the name 'Senators' is in 1901, although the nickname only apparently came into common use in the 1910s. For the period 1903–1906, the club is best known as the 'Silver Seven', although this may be a later invention.
