"Seluruh Cinta" (All of Love) is a collaborative single by Malaysian artist, Siti Nurhaliza and Indonesian artist, Cakra Khan, released on 21 October 2014. The single was first released in Indonesia as part of the Indonesian version of Siti's sixteenth solo album, Fragmen. "Seluruh Cinta" also served as the first single from Fragmen for the Indonesian market. Siti and Cakra first met during 2013 Anugerah Planet Muzik where they sang together Cakra's single at that time, "Harus Terpisah".

The collaboration came to fruition when Siti was offered by Universal Music Group (Indonesia) to do a duet with any male Indonesian singer of her choice before finally choosing Cakra as her musical partner. Composed by Krishna Balagita, they recorded the song on 29 May 2014 at MyMusic Records in South Jakarta, Indonesia in under four hours.

The song was first performed live during MNCTV's 23rd special anniversary show, "Persembahan Cinta MNCTV 23" on 20 October 2014. In 2015, the song was chosen as the theme song for a Malaysian movie, "Suamiku Encik Perfect 10".

Siti and Cakra first met and performed together during the 2013 Anugerah Planet Muzik where they sang together Cakra's single at that time, "Harus Terpisah". Afterward, she was contacted and asked by Universal Music Group (Indonesia) if she is interested to do a duet with any Indonesian singer of her choice. Admiring Cakra's unique vocals, she expressed her interest in having Cakra as her musical partner for the duet.

After the agreement has been reached, she travelled to Indonesia to record the song with Cakra at MyMusic Records' studio in South Jakarta, Indonesia on 29 May 2014. The whole recording session only took three to three hours and a half to complete. A teaser promoting the song was also shared by Siti on her Twitter account on the next day, 30 May. Prior to its exclusive release for the Indonesian market, its inclusion as the tenth track for the Malaysian version of Fragmen was actually considered.
