Glynn House is a Grade II* listed country estate near Cardinham in the county of Cornwall.

It was later owned by Ralph de Monthermer, 1st Baron Monthermer who married Edward I's daughter Joan of Acre, and subsequently by Henry V.[2] The Glynn family first occupied the estate in the mid-15th century.

[2] The present house was built in the mid to late 18th century on the site of an earlier one.

In 1805, it was rebuilt and refronted by Edmund John Glynn, High Sheriff of Cornwall, which included two Palladian wings.

In 1833, it was refurbished for Richard Hussey Vivian, which included the addition of a portico with four Doric order columns.
