The Milford Street Railway was a streetcar operating company in Milford, Connecticut, and connecting Milford to Bridgeport, Connecticut. In 1900, it was sold to the Connecticut Railway & Lighting Company (CR&L).
From 1906 to 1936, its routes were among those leased by CR&L to The Connecticut Company. In 1936, along with all other CR&L routes, the leases on its routes were voided for nonpayment.
