Megurine Luka (巡音ルカ, Megurine Ruka^?) is a humanoid persona voiced by a singing synthesizer application developed by Crypton Future Media, headquartered in Sapporo, Japan. She uses Yamaha Corporation's Vocaloid 2 and Vocaloid 4 singing synthesizing technology. Her voice is sampled from Yū Asakawa. She has performed at live concerts onstage as an animated projection. Many songs have been created with her.

Luka was developed by Crypton Future Media using Yamaha's Vocaloid 2. Her voice was created by taking vocal samples from voice actress Yū Asakawa at a controlled pitch and tone.

Megurine Luka was originally designed to be the first Vocaloid of the Character vocal series that Crypton Future Media would release and was going to be called "Hatsune Miku", designed to be capable of both English and Japanese vocals. However, the concept was put on hold and the name was used for another character, making Luka the 3rd vocal of the Character vocal series to be released instead.

She originally was going to receive an update called "Megurine Luka Append" developed for Vocaloid 2.Luka's Append vocal was used on the album Vocaloid Minzoku Chō Kyokushū (VOCALOID民族調曲集^?) for the song "Hoshizora to Yuki no Butōkai (Zeal mix)". The promotional album Vocalo Append used a beta of Luka's "Soft" Append. The vocals were announced to have been dropped in favor of Vocaloid 3 productions on December 1, 2011. Once again the Vocaloid 3 update did not occur. During the brief period her V3 website was up, the listed vocals being created for her were; Japanese/Power/Soft/Cute/Whisper/Closed/English.
