June Lockhart (June 25, 1925 – October 23, 2025) was an American actress, beginning a film career in the 1930s and 1940s in films such as A Christmas Carol and Meet Me in St. Louis. She appeared primarily in 1950s and 1960s television and with performances on stage and in film. On two television series, Lassie and Lost in Space, she played mother roles. Lockhart also portrayed Dr. Janet Craig on the CBS television sitcom Petticoat Junction (1968–70). She was a two-time Emmy Award nominee and a Tony Award winner. With a career spanning nearly 90 years, Lockhart was one of the last surviving actors from the Golden Age of Hollywood.

In 1951, Lockhart married John F. Maloney. They had two daughters, Anne Kathleen and June Elizabeth. The couple divorced in 1959. She married architect John Lindsay that same year, but they divorced in October 1970 and she never remarried. A Roman Catholic, Lockhart and her daughter Anne and actress Kay Lenz met Pope John Paul II in 1985.

Lockhart had a lifelong fascination with American presidential candidates and the media's coverage of them. Her friend reporter Merriman Smith arranged for her to travel with both major-party candidates Dwight D. Eisenhower and Adlai Stevenson during the 1956 presidential election and again with both campaigns in the 1960 election. Between 1957 and 2004, Lockhart attended many presidential briefings.

Although a child of the Greatest Generation, Lockhart embraced rock music and listened to emerging rock bands. In an interview, her Lost in Space co-star Bill Mumy stated that she took Angela Cartwright and him to the Whisky a Go Go nightclub in Hollywood "to hang out with The Allman Brothers Band". Appearing on The Virginia Graham Show in 1970 with Art Metrano and LGBT cleric Troy Perry, Lockhart confronted Graham about her moralizing tone toward gay people.

Lockhart turned 100 on June 25, 2025. She died of natural causes at her home in Santa Monica, California, on October 23, 2025. CLR
