List of international cricket five-wicket hauls by Bob Willis

In cricket, a five-wicket haul (also known as a "five-for" or "fifer") refers to a bowler taking five or more wickets in a single innings. This is regarded as a notable achievement, and, only 44 bowlers have taken at least 15 five-wicket hauls at international level in their cricketing careers. In Test cricket, Willis took 325 wickets, including 16 five-wicket hauls. The Wisden Cricketers' Almanack named him one of their cricketers of the year in 1978, and termed him "one of the world's foremost fast bowlers."
