The Royal Mill Complex is an historic textile mill site at 125 Providence Street in West Warwick, Rhode Island. The mill complex was listed on the National Register of Historic Places in 2004. It has recently been completely renovated and remodeled into 250 residential apartments. The complex also includes the Ace Dye Works mill on the south side of the river, which has been converted into lofts. A pedestrian skybridge connects the two mills.
