Nina Tower is a twin tower of 80-storey and 42-storey high-rise buildings in Tsuen Wan, New Territories, Hong Kong near Tsuen Wan West station. The tower was designed to be the tallest tower in the world at 518 m (1,699 ft). However, due to its location near Chek Lap Kok Airport, the height was restricted to the current 319.8 m (1,049 ft).

The owner of Chinachem Group later changed her plan and broke it into two towers. The lower is known as Nina Tower, symbolising the late Nina Wang or Kung Yu Sum natively, the owner of Chinachem Group; the higher is Teddy Tower, symbolising her husband Teddy Wang, who was kidnapped and has since disappeared. Despite the different tower names, the whole development is called Nina Tower.

The complex is home to a 1608-room premium hotel, Nina Hotel Tsuen Wan West, office space, shopping mall and convention & event space. A sky lobby is located at the 41st floor which connects the 2 towers.

The office of Chinachem Group and Nina Hospitality Company Limited are located at the complex.

In March 2021, L’hotel Group has been renamed Nina Hospitality to unveil its brand transformation.

The complex contains the head office of Chinachem.
