The Seaton Delaval Stakes was a Group 3 flat horse race in Great Britain open to two-year-old horses. It was run at Newcastle, and in its later years it was scheduled to take place in August.

The event was named after Seaton Delaval, a village located to the north of Newcastle. It was established in 1867, and was originally held in late June.^[1] For much of its history it took place on the day after the Northumberland Plate. It was usually contested over 5 furlongs.

The Seaton Delaval Stakes continued to be staged in June until 1961.^[2] It was switched to early August in 1962.^[3] The present grading system was introduced in 1971, and the event was classed at Group 3 level. It was extended to 7 furlongs in 1976.

The race was discontinued after 1985.
