At the beginning of their acquaintance, Ron Weasley thought Luna was weird and was not particularly interested in knowing her, even occasionally referring to her as "Loony". Luna, on the other hand, seemed to find Ron very funny but rather insensitive in his relationships at times. Ron eventually grew fonder of Luna and becoming friends with her after getting to know her better through Dumbledore's Army and her being one of the only D.A. members to come to the trio's assistance when they tried to save Sirius Black, during the Battle of the Department of Mysteries.
Ron was particularly amused by Luna's Quidditch commentary in 1996 and thought highly of her bravery. When she attended his brother Bill's wedding, Ron was further amused by her behavior and remarked that she gave "good value". However, Ron was still prone to tease Luna and scoff at her unusual beliefs at times. In 1997, Ron and Luna also fought at the Battle of the Astronomy Tower.
One year later, Ron and Luna briefly met as the two were captured in the Malfoy Manor along with Harry, Hermione, Garrick Ollivander, Dean Thomas and Griphook. They were saved by Dobby, who was killed in the process. Later that year, the two fought in the Battle of Hogwarts, where Luna, Seamus Finnigan and Ernie Macmillan saved Ron, Harry and Hermione from Dementors. Ron and Luna both survived the war.
Luna and Ron remained in contact in adulthood. In 2014, the two attended the Quidditch World Cup final along with other former members of Dumbledore's Army and family.
- “You went to the Yule Ball with Padma Patil, She didn’t enjoy it very much, She doesn’t think you treated her very well, because you wouldn’t dance with her. I don’t think I’d have minded, I don’t like dancing very much.”

- “Everyone turned to look at Luna Lovegood, who was gazing unblinkingly at Ron over the top of The Quibbler.”

"She let out a scream of mirth that caused Hedwig to wake up and flap her wings indignantly and Crookshanks to leap up into the luggage rack, hissing. Luna laughed so hard her magazine slipped out of her grasp, slid down her legs and on to the floor.
“That was funny!” Her prominent eyes swam with tears as she gasped for breath,"

“I’m supporting Gryffindor,” said Luna, pointing un necessarily at her hat. “Look what it does…” She reached up and tapped the hat with her wand. It opened its mouth wide and gave an extremely realiztic roar that made everyone in the vicinity jump. “It’s good, isn’t it?” said Luna happily. “I wanted to have it chewing up a serpent to represent Slytherin, you know, but there wasn’t time. Anyway…good luck, Ronald!”

“It’s good, isn’t it?” said Luna, who had drifted over to the Gryffindor table and now squeezed herself on to the bench between Fred and Ron."

“Nice commentary last match!” said Ron to Luna as she took back the green onion, the toadstool, and the cat litter. Luna smiled vaguely.
“You’re making fun of me, aren’t you?” she said. “Everyone says I was dreadful.”
“No, I’m serious!” said Ron earnestly. “I can’t remember enjoying commentary more! What is this, by the way?” he added, holding the onionlike object up to eye level.
“Oh, it’s a Gurdyroot,” she said, stuffing the cat litter and the toadstool back into her bag. “You can keep it if you like, I’ve got a few of them. They’re really excellent for warding off Gulping Plimpies.” And she walked away, leaving Ron chortling, still clutching the Gurdyroot.
“You know, she’s grown on me, Luna,” he said, as they set off again for the Great Hall. “I know she’s insane, but it’s in a good —”

“I like this song,” said Luna, swaying in time to the waltzlike tune, and a few seconds later she stood up and glided onto the dance floor, where she revolved on the spot, quite alone, eyes closed and waving her arms.
“She’s great isn’t she?” said Ron admiringly. “Always good value.” (DH)
“All’s fair in love and war,” said Ron brightly, “and this is a bit of both. Cheer up, it’s the Christmas holidays, Luna’ll be home!” (DH)
“Cowardly old wart,” said Ron. “Luna’s got ten times his guts.” (DH)
RedMoon is a very popular side pairing in Harmony fanfiction. Many fans who shipped Harmony during the release of Order of the Phoenix started shipping it as Luna showed some interest in Ron when the two first met. Occasionally, the two pairings are also shipped alongside Draco/Ginny or Neville/Ginny.
The ship name, Red Moon, was coined by members on the Harry Potter message board FictionAlley Park in 2003. The ship is also sometimes called Runa. On AO3 it is the tenth most written ship for Luna.
- The ship name "Red Moon" is due to Ron having red hair and Luna's name meaning moon.
