Arcadia Mills No. 1, now the Arcadia Station Lofts, is a historic mill building at 1875 Hayne Street in Spartanburg, South Carolina. The mill was built in 1903 and enlarged in 1909, to designs by Greenville J.E. Sirrine. It is a well-preserved example of textile mill engineering from the early years of South Carolina's boom period in that industry.
The mill was listed on the National Register of Historic Places in 2014. It is now an apartment building.
