Jizhou District (simplified Chinese: 蓟州区; traditional Chinese: 薊州區; pinyin: Jìzhōu Qū), formerly a county known as Ji County, is a district in the far north of the municipality of Tianjin, People's Republic of China, holding cultural and historical significance (e.g., the Buddhist Temple of Solitary Joy).

Historically, it was also known as Yuyang (渔阳; 漁陽; Yúyáng) during the Tang dynasty.

Jizhou is the only mountainous area in the Tianjin municipality, home to the renowned Mount Pan.

Known as "Tianjin's backyard", the spectacular natural scenery and numerous historical monuments, including a small section of the Great Wall known as Huangyaguan, in the county means that it is a major tourist attraction.

Jizhou is approximately 115 km (71 mi) away from the city proper of Tianjin.
