The Norwalk Street Railway was a streetcar operator in Norwalk, Connecticut. It was incorporated in 1895 to replace the Norwalk Horse Railroad Co., which had begun as the horsecar operator in Norwalk in 1862. In 1899 it was sold to the Connecticut Light & Power Co., (which in 1901 became Connecticut Railway & Lighting Co.).
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.
