The Swiss Embassy in Lisbon serves as Switzerland's diplomatic mission to Portugal, facilitating bilateral relations between the two nations while serving a small community of approximately 7,600 Swiss nationals living in Portugal. The embassy manages Switzerland's engagement with Portugal across political, economic, financial, legal, scientific, educational, and cultural affairs. The bilateral relationship is strengthened by the substantial Portuguese community in Switzerland (255,500 people, Switzerland's third-largest foreign community) and bilateral trade worth CHF 2.5 billion in 2023, complemented by an honorary consulate in Porto serving northern Portugal.
