Tahajjud Cinta is the fourteenth album by Dato' Siti Nurhaliza and also her first album to be categorised as a spiritual or religious album. The album was released on 9 September 2009, during the holy month of Ramadhan to celebrate the lack of albums in the market that propose the holistic genre.

The album was composed of eight songs. Two songs, Ketika Cinta and Pintu Rindu, were cover versions. The first was a covered version of a single by an Indonesian religious singer, Opick, whereas the latter was originally in Arabic before it was recorded into Bahasa Malaysia. The song Ketika Cinta was also used in an Indonesian film Perempuan Berkalung Sorban, together with the song Batas Asaku. At the bridge of this song, Siti Nurhaliza using her falsetto ranged at E6, the highest notes of head tone she had done.

The album was created by famous Malaysian and Indonesian composers and writers like Habsah Hassan, Audi Mok and others to suit the spiritual genre.
