Preston Luke Mommsen (born 14 October 1987) is a South African-born Scottish cricketer and former captain in international limited over formats.

[7] After four years living in Edinburgh he qualified for the Scottish National Team and was subsequently called up in June 2010 after impressing at club level.

Mommsen struck 94, and put up stands of 65 and 86 for the third and fourth wickets with Matty Cross and Freddie Coleman respectively as the team eventually piled on 288 for 9 from their 50 overs against Papua New Guinea at Bert Sutcliffe Oval in Lincoln, New Zealand.

Mommsen led Scotland into Group A for the World Cup as his second century of the tournament secured an emphatic 41-run win over UAE in the final of the qualifiers.
