Scotland's network of Third Sector Interfaces (TSIs) was established in 2011. Funded by the Scottish Government, TSIs aid the development of voluntary and community organisations, social enterprises and volunteering.

TSIs provide a vital link between the third sector and community planning.

In 2020, the national TSI network published its Manifesto for Change, outlining a vision for "resilient and empowered communities" and "a stronger, fairer and more equitable Scotland with a thriving third sector at its heart."
