Guo Jingming (Chinese: 郭敬明; pinyin: Guō Jìngmíng; born June 6, 1983), also known as Edward Guo, is a Chinese young adult writer, director, and businessman.
While in high school, Guo began publishing articles online under the pen name Disiwei ("Fourth Dimension"), which earned him the nickname Xiao Si ("Little Four"). He rose to fame by winning first prize consecutively in the 2001 and 2002 New Concept Writing Competition. With the breakout success of Ice Fantasy (2003), he established himself as a commercially successful yet critically polarizing YA writer in China, followed by bestsellers such as Rush to the Dead Summer (2006), Cry Me a Sad River (2007), and the Tiny Times trilogy (2008–2012).
As a businessman, Guo founded Island Studio in 2004, publishing Island magazine until 2006. He founded CASTOR in 2006 and Zui Co., Ltd. in 2010. The two companies played a major role in China's young adult literature market until they merged in 2019. In 2008, Guo joined EE-Media as its Literary Director. Since the 2010s, he has shifted his career focus to being a filmmaker and showrunner, with works such as Tiny Times (2013–2015), L.O.R.D (2016–2020), The Yin-Yang Master (2020-2021), My Journey to You (2023) and Veil of Shadows (2026).
