Although Worthenbury lies within the boundary of Wrexham County Borough it is situated geographically on the Cheshire Plain. The village is approximately 8 miles to the south east of Wrexham between Bangor Is y Coed and Malpas on the B5069.  The Emral and Wych Brooks converge at Worthenbury to become Worthenbury Brook, a tributary of the River Dee, which lies 1 mile to the north-west.

The Worthenbury Conservation Area was first designated in March 1971 and its boundary amended and extended in April 2000 and again in November 2009. The Worthenbury Conservation Area Character Assessment and Management Plan was adopted in November 2009.
