Baron Stanley of Alderley, in the County of Chester, is a title in the Peerage of the United Kingdom.

When the 1st Baron died in 1850, he was succeeded as 2nd Baron Stanley of Alderley and 8th Baronet of Alderley Hall by his son Edward, who was a prominent Liberal politician and notably served as President of the Board of Trade, Postmaster General and had in 1848 been created Baron Eddisbury, of Winnington in the County Palatine of Chester, in his own right.

After his death the titles passed to his son, the 5th Baron Stanley of Alderley.

On his death the titles passed to his younger brother, who preferred to be known as Lord Sheffield.

As of 2013[update] the titles are held by the latter's cousin, the 9th Baron Stanley of Alderley, who succeeded his father in that year.

He is the grandson of Oliver Hugh Stanley, youngest son of the 4th Baron.

The Right Reverend Edward Stanley, second son of the sixth Baronet, was Bishop of Norwich.
