Nadao Bangkok Co., Ltd. () is a Thai media company. Founded in 2009, it did business in artist management and television and music production, but ended those operations in 2022. The company is headed by Songyos Sugmakanan, its largest shareholder and CEO, and was previously a partially owned subsidiary of the film studio GDH 559 (itself a subsidiary of entertainment conglomerate GMM Grammy). The company was established under GDH's predecessor GTH, and initially focused only on talent management for GTH's actors. It branched into television production with the 2013 hit TV series Hormones, and since then produced television and streaming drama series including Project S, In Family We Trust, My Ambulance and I Told Sunset About You. A music production arm, Nadao Music, was launched in 2019 as a creative venue for artists under the company's umbrella, who numbered 39 in 2020, mostly young actors catering to Nadao and GDH's target audience group of 15–30-year-olds. However, the company ended its artist management as well as series and music production operations in 2022, citing its artists' growth and diverging priorities among its staff.

The company was founded as a partially owned subsidiary of film studio GMM Tai Hub (GTH) to manage its growing roster of actors and help develop their talents. It was headed by Songyos Sugmakanan, who had directed several films with GTH. During its first few years, the company focused on casting and artist management, but struggled to generate revenue. In 2012, Songyos conceived the teen drama television series Hormones to create acting opportunities for the company's teenage actors. The series, released in 2013, became widely popular, prompting the company to produce two subsequent seasons. Hormones success became a turning point for Nadao, giving it a renewed focus on content production for television as well as the streaming service Line TV, for whose 2015 launch Nadao produced the miniseries Stay. As GTH was dissolved at the end of 2015 due to internal disagreements, its holdings in Nadao Bangkok were transferred to its successor GDH 559. Nadao further expanded as it partnered with concert organizer 4nologue to launch the boy group Nine by Nine in 2018, releasing its first mainstream prime-time series In Family We Trust as part of the project. By 2020, when it released I Told Sunset About You, its staff had grown to fifty, up from
