Chapter 1 is the debut album of the South Korean pop music group g.o.d, released on January 26, 1999.

The promoted track is "To Mother" (어머님께), which the group sang for their debut televised performance on January 13, 1999.

The album was produced under difficult circumstances as g.o.d's management agency had been affected by the 1997 Asian financial crisis and cut off funding for their trainees.

However, it was not an immediate success as sales figures were comparatively low and the group did not win first place on any music programs.

The choreography for both songs was referenced in the music video of "Saturday Night" from the group's reunion album Chapter 8.
