Yoo Seong-min (born 7 January 1958) is a South Korean economist and politician known for his long service in the legislature and his role in conservative reform movements. He has served multiple terms as a member of the National Assembly and was the presidential nominee of the Bareun Party in the 2017 South Korean presidential election. Yoo is often described as a pragmatic, reform-minded conservative who emphasizes fiscal responsibility and institutional integrity.

Background and political profile

Trained as an economist, Yoo entered public life combining policy expertise with parliamentary work. Over his career he has been associated with the conservative political bloc in South Korea but distinguished himself from party hardliners by advocating internal reform, transparency, and a stronger social safety net alongside market-oriented policies. His public image is tied to a reputation for straightforward speech and an emphasis on ethical conduct in politics.

Parliamentary work and policy focus

As a legislator Yoo has focused on economic and fiscal issues, budgeting, and regulatory reform. He has participated in parliamentary committees related to finance and public accounts and has spoken frequently about the need to modernize regulation, curb excessive concentration of corporate power, and protect vulnerable groups through targeted welfare measures. Yoo's approach blends conservative economic principles with cautious social policy measures intended to reduce inequality.

Key themes associated with Yoo's career include:

  • Fiscal discipline and transparent budgeting
  • Market-friendly reform balanced with social protections
  • Commitment to political ethics and intra-party accountability

Yoo has served as a representative in the National Assembly for many years and has been active in legislative debates on governance and economic policy. His role in the legislature has given him visibility as a policy-oriented politician rather than a purely populist figure.

In 2016–2017, amid a major political crisis triggered by the impeachment of President Park Geun-hye, Yoo joined colleagues who broke from the ruling party to form or align with new conservative groupings that sought to uphold reform and accountability. He became the Bareun Party's presidential nominee in 2017, running on a platform of clean governance and pragmatic reform. Although his campaign did not succeed in winning the presidency, it reinforced his standing as a voice for change within South Korea's conservative movement.

Yoo's career illustrates broader tensions in South Korean politics between traditional party loyalties and demands for transparency and reform. Observers note his continuing influence as a figure who seeks to reconcile market-friendly policies with institutional renewal and social responsibility.
