The Union of Greens and Farmers (Latvian: Zaļo un Zemnieku savienība, ZZS) is an agrarian political alliance in Latvia.

[15][16][17] While the alliance's formal leader is Edgars Tavars, its leading figure and chief financial supporter is the oligarch Aivars Lembergs.

It became part of the governing coalition, and LZP chairman Indulis Emsis, who served as Prime Minister briefly in 2004, became Speaker of the Saeima.

Aivars Lembergs was the candidate of the Union of Greens and Farmers for the position of Prime Minister in 2006, before being charged with corruption, fraud, bribery, money laundering and abuse of elected office on 20 July 2006.

This move required EFDD to co-opt a member of Poland's Congress of the New Right to remain eligible for parliamentary group status.

In January 2016, after the resignation of Prime Minister Laimdota Straujuma, Liepāja Party member Māris Kučinskis became the head of government.

After the 2018 Latvian parliamentary election, ZZS lost ten seats and ultimately in 2019 became a part of the opposition to the Kariņš cabinet.

In July, the Greens and the Liepāja Party joined the Latvian Association of Regions and a political NGO led by construction contractor Uldis Pīlēns in forming the United List alliance.
