Safeco Corporation was the 23rd largest American national insurance company. It had naming rights to the Seattle Mariners’ baseball stadium, Safeco Field.

Safeco was founded in Seattle, Washington in 1923 by Hawthorne K. Dent as the General Insurance Company of America, a property and casualty insurer. This name is still used by Safeco on some of its insurance products.[1] Thirty years later the company founded the Selective Auto and Fire Ensurance Company of America, or SAFECO (i.e., S.A.F.E. Co.).
