Justin Ernest George Morneau ("MOR-know") (born May 15, 1981 in New Westminster, British Columbia) is a Canadian Major League Baseball player who is currently the Minnesota Twins' starting first baseman. In 2006, he was awarded the American League Most Valuable Player award. In 2008, he became the first Canadian to win the Home Run Derby. He is considered one of the premier first basemen in the major leagues.

Morneau is the youngest son of George Morneau, a hitting coach for many softball and baseball teams, childcare worker, and sporting goods store owner, and Audra Sinclair, an elementary school teacher and former fastpitch softball player. Justin has an older brother, Geordie. His father once played hockey for the Brandon Wheat Kings and attended the training camp of the Minnesota North Stars, coincidentally a team representing the same city in which his son would later play baseball.

Morneau grew up in New Westminster, British Columbia, the historic "Royal City," adjacent to Vancouver, where he played hockey for the local minor team, the New Westminster Royals, and emerged as a star goaltender, playing for teams a year older than he was.
