The Best Denki Co., Ltd. (株式会社ベスト電器, Kabushiki-gaisha Besuto Denki) is a Japanese electronics retailer with outlets across Japan, Singapore, Indonesia and Malaysia.

Previously, in Singapore and Hong Kong, it was known as "Yaohan Best", when it started operations there in 1985.

When Yaohan declared bankruptcy in 1997, it was spared from liquidation since all the goods and products in the department are owned by Best Denki.

All of the stores (under the name The Best Connection) closed in 1998-1999 due to the Asian financial crisis.

Best Denki's first store outside Japan was located in Singapore, which opened in 1982.
