The Walker-Smith Baronetcy, of Broxbourne in the County of Hertford, is a title in the Baronetage of the United Kingdom.
It was created on 18 July 1960 for the Conservative politician Derek Walker-Smith.
On his retirement from the House of Commons in 1983 he was further honoured when he was created a life peer as Baron Broxbourne, of Broxbourne in the County of Hertfordshire.
The life barony became extinct on his death in 1992 while he was succeeded in the baronetcy by his son, the second holder of the title.
The heir apparent is the current holder's son, Alexander Jonah William Walker-Smith (born 2017).
