The Hôtel de Grady is a hotel particulier in Liège in Belgium, sited at 5 rue Hors-Château.

It was first commissioned in 1765 by Nicolas de Spirlet, privy counsellor to the prince bishop of Liège.

The Grady family had been tanners in Outremeuse but they gained a fortune by trade and included lawyers, a deputy and a number of major magistrates.

Enriched by trade, the family began a social ascent which made its members lawyers, aldermen, deputy and high magistrates.

The Hôtel de Grady was listed as a Walloon Region's real estate heritage in 1941.
