Vladimir Peter Sabich Jr. (January 10, 1945 – March 21, 1976) was an American alpine ski racer, a member of the U.S. Ski Team on the World Cup circuit in the late 1960s. He competed at the 1968 Winter Olympics and was the pro ski racing champion in 1971 and 1972. Sabich was killed by gunshot under controversial circumstances involving Claudine Longet in 1976.

The grandson of Croatian immigrants, Sabich was the second child of Vladimir (1915–2001) and Frances Sabich (1911–2003). His lifelong nickname "Spider" was given by his father as a result of thin arms and legs at a premature birth. Spider's father was an officer of the California Highway Patrol and had volunteered in World War II as a B-25 pilot in the Air Force; he was held as an internee in Siberia by the Soviets for a year after his plane was shot-up over northern Japan and forced down near Vladivostok. After the war, Vlad was a test pilot and then returned to his job with the CHP in Sacramento, and in 1950 he was transferred to Kyburz on Highway 50, southwest of Lake Tahoe.

The three Sabich children (Mary, Spider, and Steve) learned to ski at Edelweiss ski area, about a dozen miles (20 km) up the highway, a mile past Twin Bridges. They attended a one-room school in Kyburz, Silver Fork Elementary, and went to class in the summer and skied during the winter, frequently arriving in their father's patrol car.

Spider and Steve were altar boys at the Catholic church across the highway from the ski area (Chapel of Our Lady of the Sierras) and would often strap on their skis immediately following Mass. Their ski coach was Lutz Aynedter, a downhill champion from the 1940s who emigrated from Germany to California after the war. He taught the Sabich boys European-style ski racing, and Spider and Steve became junior stars among the fearless young racers of Edelweiss, who became known as the "Highway 50 Boys." The Edelweiss ski area closed in the early 1960s after a poor snow year; the location is now called Camp Sacramento.

Despite their outdated equipment, Spider and Steve established themselves as top junior ski racers in northern California in the early 1960s. After graduation from El Dorado High School in Placerville, both were offered skiing scholarships to the University of Colorado in Boulder, one of the dominant collegiate programs of the era. Head coach Bob Beattie was also the coach of the U.S. Ski Team, and the national team was heavy with CU skiers. While at Colorado, Spider majored in aeronautical engineering and was selected to the national team. Steve's career was ended by a knee injury while at CU.

Sabich skied on the World Cup circuit for its first four seasons, and finished fifth in the slalom in the thick fog at the 1968 Winter Olympics at age 22. His sole World Cup victory came two months later in April, a slalom at Heavenly Valley at South Lake Tahoe, just east of his hometown of Kyburz. He finished eighth in the slalom standings for the 1968 season and was the U.S. downhill champion.

Sabich reached the World Cup podium (top three) three more times in the slalom in 1969. He finished seventh in the 1969 season standings for the slalom and 11th overall, but fell out of the top ten in the slalom the following year.

Sabich had 18 top ten finishes in Olympic and World Cup competition: two in downhill, three in giant slalom, and 13 in slalom.
