Linda Jacobs, who is a keeper at Jungle Island Zoo, wants the apes to use apps to tell keepers what they want to eat.
Jacobs said: "They have all the intelligence they need to communicate with us.
"But what they don't have is developed vocal chords and voiceboxes. This gives them a voice."
Watch the video below to see the orangutans using the iPads:
Jacobs explained: "Some of them like carrots more than they like beets. And don't we all want to have that choice?
"I don't want to eat the same thing every day that someone else picks for me. I want them to have a choice over their lunches."
The zoo also hopes that the orangutans will be able to communicate with visitors.
It plans to connect the ape's iPads with interactive screens that visitors can use.
