Located off North Queen Street, this street is probably named from Sea View Cottage, first recorded in 1814. This was a different house from Sea View, situated a little further out on Shore Road, which gave its name to Crusaders F.C. football ground and two other streets: Seaview Drive and Seaview Gardens.
In 1835 a Mr. Simms was resident at Seaview-cottage (Matier’s Belfast Directory). He was a partner in the book publishing and stationery business Simms & McIntyre operating at 20, Donegall Street.
Application of Mr R.J. McConnell two new streets off York Road be named Parkmount Street and Seaview Street (Town Improvement Committee, 5th June 1889).
