Cornelis Arie "Kees" Verkerk (born 28 October 1942) is a former speed skater from the Netherlands.

As a result of his performances, he received the Oscar Mathisen Award in 1966 and 1967, the first skater to win this award twice, although until 1967, skaters were not eligible to win it more than once.

In 1973, together with Ard Schenk and a dozen other skaters, Verkerk joined in a newly formed professional league, but this lasted only two years.

Verkerk met his future Norwegian wife in 1972 and has lived in Norway since his speed skating career ended.
