Swak na Swak (lit. 'That Fits'), formerly known as Kabuhayang Swak na Swak (Perfectly Fit Business), is an entrepreneurial and informative show produced by Bayan Productions which was aired weekend mornings on ABS-CBN and worldwide via The Filipino Channel. It premiered on August 22, 2006, with Amy Perez and Chase Tinio as the show's original hosts. The program features ways, means and techniques of how to start, set up and maintain a certain business. The show aired every Saturday and Sunday at 7:00 a.m. (PST) except for some ABS-CBN Regional stations, where it was broadcast at an earlier time of 5:30 a.m. to make room for locally produced ABS-CBN Regional news programs like the Saturday editions of Maayong Buntag Kapamilya, Panay Sikat, and Maayong Buntag Mindanao.

From May 3, 2020, the show has been temporarily suspended airings due to the temporary closure of ABS-CBN because of the cease and desist order of the National Telecommunications Commission (NTC), following the expiration of the network's 25-year franchise granted in 1995. It was carried over by Kapamilya Channel when it was launched a month after.

On April 25, 2021, ANC ended its simulcast for Swak na Swak, and ANCX programming took its place on May 2, 2021.

The show concluded on September 26, 2021, after 15 years of airing and the temporary closure of Bayan Productions, and was replaced the following week by a replay of earlier seasons of G Diaries.
