A spokesman for the Ayrshire airport said the crew of the Ryanair passenger jet, which had flown from Faro in Portugal, were ordered to perform "a go-around".
He said the aircraft landed safely shortly after the incident.
The spokesman said the airport was investigating how the deer had got in to the "vicinity of the airfield".
Sandra Bell, from Kilmarnock in Ayrshire, told BBC Scotland: "We were almost down. We were coming over the last farm when we pulled back up again.
"Everybody was looking at one another, wondering what was going on."
She said it was only when they came around to land again that the passengers were informed of what had happened.
The flight landed safely and there were no injuries, the report said.
