Lukagaminette is the poly ship between Kagami Tsurugi, Marinette Dupain-Cheng and Luka Couffaine from the Miraculous Ladybug fandom.

Canon
While Luka and Kagami don't know really each other, they are both friends with Marinette. Kagami had first seen Marinette as a love rival, before becoming her friend in "Ikari Gozen". Luka is in love with Marinette. So the two of them go on "date" at the ice rink in "Frozer." There, they bump into Kagami, who had taken a few glimpses of them whenever she caught Adrien looking at Marinette while Luka is close to her side and follows Adrien's gaze on her. Kagami had skated passed Luka when she went to help Marinette get back in her feet.

In "Desperada," while skipping fencing class for the day, Kagami visits the two at Luka's boat with Adrien as they got to see him and their friends. She sees Luka teaching Marinette a few notes on his guitar. And mistakes them for boyfriend and girlfriend. After Viperion helps Ladybug and Cat Noir defeat the titled villain, they spend the rest of the day playing music with his band, while Kagami watches them. She tells Marinette to quickly make her choice between Luka and Adrien as love is something that people can't have second chance at. While Alya reminds both girls that either of the two boys have made their own choices yet.

Fanon
Lukagaminette is a rare poly Miraculous Ladybug ship, as Luka and Kagami don't know each other well.

Because both Luka and Kagami are temporarily entrusted with Miraculouses, the Snake Miraculous and the Dragon Miraculous, many fans hope that future episodes in the series would have Viperion and Ryuko helping Ladybug, together as a team of three. In the season three episode, "Timetagger", it's revealed that during the time of their future adulthood, Ladybug and Cat Noir have assembled a team of fellow Miraculous holders. This has led many fans to theorize that this team may include both Ryoko and Viperion's talents, some of the most useful Miraculouses. The fact that they'll be facing a different holder of the Butterfly Miraculous, also revealed in that episode, who might not know who Ryuko truly is, making it safe for Kagami to become the dragon-themed heroine again without placing her family and loved ones in danger. The same with Luka, since the season three finale has the current Hawk Moth uncovering Viperion's and the other temporally heroes' secret identities.

The ship currently has less than 10 works written. However, there are quite a few fan arts for the ship on Tumblr.

Trivia

 * According to Feri González, both Luka and Kagami aren't limited to the role of alternate love interest.
 * The out of order released episode "Party Crasher" reveals that Luka became one of Ladybug and Cat Noir's temporary allies, holder of the Snake Miraculous. His name of choice was Viperion and he was given the power of Second Chance, which grants the ability to go about two minutes back in time an unlimited amount of times.
 * Fans knew for some time that Luka would receive the Snake Miraculous, as leaks of the concept art for Viperion and his name were leaked. At this time, we also saw Kagami's hero form, Ryoko, released, along with Marinette as Multimouse. This prompted fans to draw fanart with all three together in their new superhero forms.
