In 2006 the Virginia High School League (VHSL), the sanctioning body for Virginia public high school athletics, recognized lacrosse as an interscholastic sport and established an official state championship tournament. From the 1970s through the 2004-2005 school year, lacrosse was played as a club sport by Virginia public high schools. From 1991 through 2005, the winner of the unofficial Northern Region tournament (Fairfax County, Arlington County, and the City of Alexandria public schools) was also recognized as the unofficial Virginia state champion even though other public high schools, primarily in the Charlottesville and Richmond areas, also played club lacrosse. Robinson won the unofficial Virginia state championship in 1991, 1993, 1994, 1996, 1998, 2001, and 2002. Robinson also won the first two official VHSL sanctioned state championships in 2006 and 2007, and then again in 2014, 2015, and 2016. Robinson won Region titles in 1988, 1989, 1991, 1993, 1994, 1996, 1998, 2001, 2002, 2007, 2010, 2014, 2016, 2018, and 2019; and district titles in 1988, 1989, 1991, 1992, 1993, 1994, 1995, 1996, 1998, 2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2010, 2014, 2016, 2017, and 2018. Since obtaining varsity status in 1991 the Robinson boys' team has a team record of 334 wins, 91 losses and 1 tie.
