Datuk Tey Seu Bock (born 21 February 1973) is a retired Malaysian professional badminton player.

As a player, he was active in both men's singles and doubles until his retirement.

Following limited success in his playing career, he turned to coaching and remained as an assistant to Misbun Sidek for a large number of years acting as sparring partner to players such as Rashid Sidek, Muhammad Roslin Hashim and eventually Lee himself.

Coaching Tey joined the BAM in 2002 and became an understudy to Misbun Sidek. Following Misbun's resignation from the BAM in 2010, Tey was chosen to take over coaching responsibilities of the men's singles department and take world No. 1 Lee Chong Wei under his wing. Under his watch, Lee would go on to clinch, among many, two more Olympic silver medals, four world championships silver medals and three All England Open Badminton Championships men's singles titles.

Following the coaching reshuffle at BAM in 2017, Tey was re-assigned and has since served as head coach of Malaysia's national women's singles department.

In May 2020, the BAM once again restructured their national coaching setup which saw Tey returning to the men's singles squad as assistant to head coach, Hendrawan. Another Indonesian, Indra Wijaya, succeeded Tey as women's singles head coach.
