Government High School No. 1 (Boys), Dera Ghazi Khan
(commonly known as Govt. Boys High School No. 1 DG Khan or ہائی سکول نمبر ون),
stands as one of the oldest and most prestigious educational institutions in southern Punjab, Pakistan.

Established in the late 19th century (around the 1890s during the British colonial era), the school was upgraded to high school status in 1910. This makes it a historic landmark in the region's educational landscape, often regarded as the premier boys' school in Dera Ghazi Khan city.

Originally linked to earlier community efforts (with some historical references suggesting roots in pre-partition institutions), it has evolved into a key government-run center of learning under the Punjab Education Department. At times, it has operated under special initiatives like the Danish Schools Authority or as a Center of Excellence, reflecting efforts to elevate quality education in the area.

The school is renowned for providing quality secondary education (from class 6 to 10, leading to matriculation), combined with strong emphasis on moral training (تربیت), discipline, and extracurricular activities. It has produced numerous distinguished alumni, including doctors, engineers, bureaucrats, politicians, and professionals who have contributed significantly to society.
With a large campus featuring multiple classrooms, playgrounds, and facilities, it continues to serve thousands of students. Its iconic red-brick architecture and central location in the city make it a recognizable symbol of educational heritage in DG Khan.
The motto visible at the entrance—"Enter to Learn, Leave to Serve"—perfectly captures its ethos of nurturing knowledgeable and responsible citizens for Pakistan.

This venerable institution remains a source of pride for generations of residents in Dera Ghazi Khan, upholding a legacy of excellence in education amid the cultural and historical richness of the region.
