"Elaine was so beautiful. So beautiful. So beautiful."
– Robert Johnson, 2267 ("The Deadly Years")
Elaine Johnson was a 27-year-old Human female born in 2240, who was married to Robert Johnson. During the 2260s, she was a member of the scientific expedition at the experimental colony on Gamma Hydra IV.
When the planet went through the trail of a comet in 2267, radiation hit the planet, causing all the colonists to age rapidly and die of premature old age. Elaine survived until the arrival of the USS Enterprise and met the landing party with her husband. She was brought to the Enterprise's sickbay, but died soon afterwards. (TOS: "The Deadly Years")
Elaine Johnson was played by Laura Wood.
