Mathias David Grönberg (born 12 March 1970) is a Swedish professional golfer who now lives in the United States. He has played on the European Tour and PGA Tour.
In 1970, Grönberg was born in Stockholm, Sweden. In 1988, at the age of 18, Grönberg won the Swedish Boys Championship.
In 1990, Grönberg won the British Youths Open Amateur Championship. That year he helped Sweden to win the Eisenhower Trophy and also won the individual title.
In 1990, Grönberg turned professional. After starting out on the second-tier Challenge Tour, he was a member of the European Tour from 1994 to 2003, winning four events in that timespan. His best finish on the European Tour Order of Merit was tenth in 1998.
However, Grönberg was keen to join the PGA Tour in the United States, repeatedly entering its Qualifying Tournament. In 2003, after six failed attempts, he earned medalist honors. Grönberg had difficulty settling on the PGA Tour and after his 2005 second season he had to return to the Qualifying Tournament to retain his card, which he did. His best finish in a tour event was a 3rd place finish at the 2007 Valero Texas Open, three behind Justin Leonard.
In 2008, the first Mathias Grönberg Trophy event took place in Sweden. Grönberg's goal is to make golf more popular with young children in his home country. It is an annual event that is being played at Kårsta Golf Club.
In 2009, Grönberg won his first title on the Nationwide Tour at the Melwood Prince George's County Open where he won by six strokes over Esteban Toledo and Justin Bolli. He finished 24th on the money list to earn his 2010 PGA Tour card.
Grönberg is married to Tara. They have three children.
