Megan Ruby Balks NZAM (born 1960) is a New Zealand Antarctic soil scientist and former lecturer at the University of Waikato.

Born in 1960,[1] Balks was raised on a sheep farm in the Wairarapa, giving her an appreciation of the environment, and she wanted to become a geologist.

[2] Balks lectured at the University of Waikato from 1988 until she left in 2018, and mentored 10 Antarctic soil research graduate students.

Around the 1980s the two moved to Dunedin due to Balks' work in Central Otago, and so that Errol could study land surveying.

They now live in Waikato and have their own nature reserve, where they have a breed of sheep that produces a fibre that Balks uses in a craft hobby.
