Aloysius Arnolds (December 17, 1835 - February 9, 1896) was an American farmer who served as a local official and as a member of the Wisconsin State Assembly.
He received a common school education and became a farmer.
He emigrated to the United States, settling in New Coeln in the Town of Oak Creek in 1847.
In 1876, Arnolds was elected as a Democrat to the Assembly's 11th Milwaukee County district (the Towns of Franklin, Greenfield, Lake and Oak Creek) for the 1877 session, with 1,279 votes to 979 for Republican R. B. Brunn (the incumbent, Hubert Lavies, had been a member of the now-crumbling Reform Party, and was not a candidate).
