Housed in the brewery's old art deco headquarters in Hunslet Road, The Tetley hosts a programme of exhibitions, workshops and events throughout the year.
And tomorrow, visitors to its cafe and bar will be able to claim a pint of Tetley's No.3 Pale Ale for every item ordered from the venue's special Yorkshire Day menu.
Announcing the special partnership, The Tetley said: "Founded in Leeds in 1822 by one of Yorkshire's most celebrated entrepreneurs, Joshua Tetley, Tetley's know how to brew a proper pint.
"The No.3 Pale Ale has been inspired by the original recipe developed in 1868, uses the same double strain yeast and is brewed back in The Leeds Brewery.
"So, if you do one thing this Yorkshire Day, make sure you have a proper pint."
Visitors must quote 'Yorkshire Day' to get the deal when placing their order.
The offer is only available on August 1 between noon and 9pm.
