Landers was born in Philadelphia, Pennsylvania and was raised in Rockland County, New York. She is the daughter of Ruth Landers, and is the younger sister of actress Audrey Landers. Due to their physical resemblance, many people assume Judy and Audrey are twins, though Judy is actually two years younger. She studied at the American Academy of Dramatic Arts, then attended the Warren Robertson Dramatic Training School before training at the Juilliard School of Music.
Landers has appeared in several films, including Goldie and the Boxer (1979), The Black Marble (1980), Hellhole (1985), Doin' Time (1985), Deadly Twins (1985), Stewardess School (1986), Armed and Dangerous (1986), Ghost Writer (1989), Club Fed (1990), Dr. Alien (1989), and The Divine Enforcer (1992). She has also appeared in several television series, including The Love Boat (1977), Happy Days (1977), Night Court (1984), Charlie's Angels (1978), Vega$ (1978-1979), B. J. and the Bear (1979), The Jeffersons, Buck Rogers in the 25th Century (1980), Madame's Place (1982–1983), L.A. Law (1986), The Fall Guy (1982), and ALF. She appeared in two different episodes of the original Knight Rider (as two different characters), and two episodes of The A-Team (again as two different characters).
Landers has often worked with her sister and mother in the business, including collaborating with Audrey on the children's show The Huggabug Club (1996). The sisters were on the cover of the January 1983 issue of Playboy magazine and in a non-nude pictorial. The sisters, along with their mother Ruth, produced the family film Circus Island (2006).
In November 1987, Landers married Tom Niedenfuer, who was a relief pitcher for the Los Angeles Dodgers baseball team. They have two daughters: Lindsey, born 1989; and Kristy, born 1991. The couple now resides in Sarasota, Florida.
