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.
"That, on the application of Mr R. J. McConnell, two new streets off York Road be named Parkmount Street and Seaview Street". (5 June 1889).
