Lambertus "Bep" van Klaveren (26 September 1907 – 12 February 1992) was a Dutch boxer, who won the gold medal in the featherweight division at the 1928 Summer Olympics in Amsterdam.

Van Klaveren remains the only Dutch boxer to have won an Olympic gold medal.

After his Olympic success in 1928, he received a hero’s welcome in his hometown Rotterdam and was presented to the Dutch Queen and her prince consort.

During his professional tenure, van Klaveren fought on four continents and won fights against Ceferino Garcia and Kid Azteca.

He then moved to Australia with his second wife, an Australian nurse, and worked there as a sports teacher, dock worker, bouncer, and boxing instructor.
