Adolf Hofrichter (16 March 1857 – 14 October 1916) was a German plumber and locksmith who became a Social Democratic (SPD) editor, party official and politician.
He stood for election to the Reichstag (parliament) in a succession of general elections between 1893 and 1912.
Nationally, the Social Democratic Party received more votes than any other party in every general election between 1890 and 1912, but their votes were concentrated in urban electoral districts which had far larger electorates than the more conservative rural districts: 1912 was the first time that the party won the largest number of seats.
It was also the first time that Adolf Hofrichter, elected to represent Cologne City Electoral District, won a seat in the Reichstag.
He remained a member till his death four an a half years later.
