Alpha Tower is a commercial building in Birmingham, England. It was built to a design by George Marsh of Richard Seifert & Partners as the headquarters of the commercial television company ATV and part of the companies' production studio complex known as ATV Centre. Now operated by the developers GVA Grimley, it provides office space for a number of companies and organisations, including Network Rail, Birmingham Arts Marketing, Jacobs Engineering, Glide Utilities, and the Criminal Cases Review Commission. Birmingham City Council vacated the building in 2010.

It is a landmark and is a Grade A locally listed building. It was nominated for listed building status by The Twentieth Century Society in 2002, although the owners applied for a Certificate of Immunity from Listing.

An adjacent shorter tower was planned but was never built. The site of the tower that was not built is now proposed as the location for another, but taller building called V Building as part of the wider Arena Central development which will redevelop the now-closed studio facilities at ATV Centre. V Building will be 147 metres tall.
