Martha Wright (born Martha Lucile Wiederrecht; March 23, 1923 – March 1, 2016) was an American actress and singer best known for her performances on Broadway and on television.

A native of Seattle, Wright sang on the radio and played roles in musical theatre and opera as a teenager. She moved to New York City and debuted on Broadway by age 21, where she soon found success as Mary Martin's replacement in both South Pacific and The Sound of Music. She also continued to sing on the radio. From the mid-1950s Wright also performed on television, including in her own show. By the late 1960s she had curtailed her performances but returned for a few engagements in the 1970s and 1980s.
