The Proximus Towers (French: Tours Proximus; Dutch: Proximustorens) are twin skyscrapers on the Boulevard du roi Albert II/Koning Albert II-laan in the Northern Quarter central business district of Brussels, Belgium.

The towers are both 102 metres (335 ft) tall to the roof, making them some of the tallest buildings in Belgium, and Tower 1 has a spire reaching 134 metres (440 ft) high with a Belgian flag mounted on top.

The two towers are linked by a 30-metre-long (98 ft) glass skyway between the 25th and 26th floors of each building.

[1] The towers were originally conceived as part of an eight-building Brussels World Trade Center (WTC) complex, but were splintered off into a separate project.
