Rexlon Ting Gatchalian (Chinese: 張僑倫; pinyin: Zhāng Qiáolún; born January 21, 1979) is a Filipino politician serving as the 28th Secretary of Social Welfare and Development since 2023.

He completed his primary and secondary education at Xavier School in San Juan, Metro Manila.

He served as an intern of Political Affairs Group in 2000 and as a paralegal for Williams and Connelly, LLP in Washington, D.C. in 2001.

[4] Gatchalian first ran for representative of the 1st district of Valenzuela, in 2004 but lost to outgoing Mayor Bobbit Carlos.

It was also during his first term as Representative that he was elected as National Spokesperson for the political party Nationalist People's Coalition (NPC).

Other programs developed under his term as a Mayor include: After completing his projects for the 5 Pillars, Gatchalian's second wave of undertakings focused on transforming Valenzuela City into a more liveable one.

His notion of a liveable city essentially implies the presence of a leveled up infrastructure network and integrated sound protocols on logistics and management that will enable the city to respond to disasters and other challenges - hence, the birth of the ALERT Center (Allied Local Emergency and Evacuation Response Teams).

The ‘little city halls’ house the fundamental satellite offices of the local government, such as the barangay health stations, fire substations, Serbisyo Centers (satellite offices for the payment of business permits, real property, and other government taxes), and many more.

The park is adorned with hundred-years old luscious trees, fountain, memorial marker commemorating war veterans and statues of Pío Valenzuela and José Rizal.

[34] On January 31, 2023, Gatchalian was appointed by President Bongbong Marcos as Secretary of Social Welfare and Development; he took oath on the same day.

The citations profess the city's economic accountability, livability and disaster preparedness, outstanding employment and micro-entrepreneurship development programs, timely health and social protection policies, and sound implementation of peace and order advocacies.
