Thomas Assheton Smith (the younger) (2 August 1776 – 9 September 1858) was an English landowner and all-round sportsman who was notable for being one of the outstanding amateur cricketers of the early 19th century.

He was also known for his pioneering work on the design of steam yachts in conjunction with the Scottish marine engineer Robert Napier.

He had five sisters and an elder brother, John, who was expelled from the family after marrying a servant, paving the way for Thomas to become his father's heir.

[3] Smith was a hard hitting right-handed batsman and made 45 known appearances in first-class matches up to the 1820 season.

[6] Assheton Smith spent summers at his Vaynol Park estate in North Wales, on the shore of the Menai Strait and close to the family's slate quarries at Dinorwic.

[9][10] Smith died at Vaynol Park, Bangor, Caernarvonshire on 9 September 1858 and was buried at Tedworth, where he lived in his later years.
