Okells Brewery is a regional brewery founded in 1850 by Dr. William Okell in Douglas, Isle of Man.^[1]

Dr. William Okell, a Cheshire surgeon, started Okell's Brewery in Castle Hill, Douglas in 1850. By 1874 Dr. Okell owned many of the pubs on the island, had convinced Tynwald, the island's parliament, to create an act ensuring the purity of beer brewed on the Isle of Man (Isle of Man Pure Beer Act), and built The Falcon Steam Brewery just off Broadway in Douglas. This imposing Building still stands today as Sheridan Apartments.

In 1972 Okells was bought by Heron & Brearley, a local drinks company. Then, in 1986, it was merged with Castletown Brewery and H&B was renamed as The Isle of Man Breweries which later reverted to the name Heron and Brearley

In August 1994 Okells moved to a new purpose built brewery built inside the existing Heron & Brearley Warehouse outside Douglas.

Beers are available on the Isle of Man and in the UK. Okells have five UK pubs:

• Thomas Rigby's, Liverpool
• The Fly In The Loaf, Liverpool
• The Lady of Mann, Liverpool,
• Bear and Billet, Chester

Plus fifteen pubs in the Market Town Taverns pub chain bought by Heron and Brearley.

The beer is also available through Morgenrot UK beer distributors. Bottled beer is also available in the Isle of Man, Sweden and Finland.
