Kenneth Douglass Hubbs (December 23, 1941 – February 13, 1964) was an American professional baseball player. He played in Major League Baseball as a second baseman for the Chicago Cubs from 1961 to 1963. Hubbs died at age 22 when the private plane he was piloting crashed in a snow storm near Provo, Utah prior to the 1964 season.

In his short big-league career he was an excellent fielder, already earning a Gold Glove Award; assessments of his hitting were more mixed, as he was still developing as a hitter. In 1962, becoming the first rookie in baseball history to win a Gold Glove Award, Hubbs set several fielding records and convincingly won the 1962 National League Rookie of the Year Award. At the time of his death, Hubbs was among the best defensive second basemen in the game.

Hubbs was born in Riverside, California, on December 23, 1941, the son of Eulis and Dorothy Hubbs. The family resided in nearby Colton, California. Ken was the second oldest of five boys, raised with brothers Keith, Gary, and twins Kirk and Kraig.

When he was a few months old, in the spring of 1942, Hubbs suffered a ruptured hernia, and wore a truss for five years until it healed while he was in kindergarten. A doctor had told the family that Hubbs "will never be able to do things other kids can do in sports."

Hubbs played in the 1954 Little League World Series, as his Colton little league team advanced and represented California. California beat Virginia in the first round and Illinois in the second. In the final game of the Series, the team from Schenectady, New York beat California 5–3. Two future big league players played on the Schenectady team: Jim Barbieri and Billy Connors. Connors and Hubbs would become minor league teammates. Highlights of Hubbs playing defense at shortstop were captured on film. The video includes a play where Hubbs ran from the shortstop position to back up the second baseman and caught a bloop fly into short right field. Hubbs had stepped in a hole during a picnic, just before Colton's trip to the Little League World Series, breaking his toe. Hubbs played the entire tournament with the injury, hobbling around the bases when he hit a home run.

At Colton High School, Hubbs was a four sport athlete. He excelled in three sports, baseball, basketball and football at a national level and also competed in track as a high jumper. Honored by the California Interscholastic Federation in all three sports, Hubbs was an All-Southern Section for two years in football, basketball and baseball, an achievement matched at the time, 1959, by only three others: Glenn Davis, Bill McColl and Marty Keough.

A gifted athlete, Hubbs could pitch with either arm and at 6'2", could stand flat-footed under a basket, jump and dunk a basketball behind his head with both hands. In 1958–1959, he was a high school All-American in two sports, football (quarterback) and basketball. He was recruited by the University of Notre Dame to play quarterback and offered a scholarship by UCLA's John Wooden to play basketball.

In 1958, in a well-publicized basketball game at Long Beach City College against Santa Maria High School, Hubbs made a half-court shot to end the first half. He followed up by scoring five points in the last 23 seconds of regulation, including a jumper at the buzzer to send the game into overtime, scoring 23 points in a Colton 53–49 win.
