St Andrew's, known for sponsorship reasons as St. Andrew's @ Knighthead Park, is an association football stadium in the Bordesley district of Birmingham, England. It has been the home ground of Birmingham City Football Club for more than a century. From 2018 to 2021, it was known as St Andrew's Trillion Trophy Stadium.

Bordesley is an area of Birmingham, England, 1.2 miles (2 km) south east of the city centre straddling the Watery Lane Middleway ring road. It should not be confused with nearby Bordesley Green. Commercial premises dominate to the west of the ring road, but much of this area is to be redeveloped. Blocks of residential apartments are planned and set for completion from the mid-2020s onwards. The largely residential area east of the ring road was renamed Bordesley Village following large scale clearance of back-to-back houses and redevelopment in the 1980s and 90s. Bordesley is the real life setting of the BBC series Peaky Blinders, and home to Birmingham City Football Club's ground, St Andrew's.
