The Stability and Growth Pact (SGP) is an agreement, among all of the 27 member states of the European Union, to facilitate and maintain the stability of the Economic and Monetary Union (EMU). Based primarily on Articles 121 and 126 of the Treaty on the Functioning of the European Union, it consists of fiscal monitoring of members by the European Commission and the Council of the European Union, and the issuing of a yearly recommendation for policy actions to ensure a full compliance with the SGP also in the medium-term. If a Member State breaches the SGP's outlined maximum limit for government deficit and debt, the surveillance and request for corrective action will intensify through the declaration of an Excessive Deficit Procedure (EDP); and if these corrective actions continue to remain absent after multiple warnings, the Member State can ultimately be issued economic sanctions. The pact was outlined by a resolution and two council regulations in July 1997. The first regulation "on the strengthening of the surveillance of budgetary positions and the surveillance and coordination of economic policies", known as the "preventive arm", entered into force 1 July 1998. The second regulation "on speeding up and clarifying the implementation of the excessive deficit procedure", known as the "dissuasive arm", entered into force 1 January 1999.

The purpose of the pact was to ensure that fiscal discipline would be maintained and enforced in the EMU. All EU member states are automatically members of both the EMU and the SGP, as this is defined by paragraphs in the EU Treaty itself. The fiscal discipline is ensured by the SGP by requiring each Member State, to implement a fiscal policy aiming for the country to stay within the limits on government deficit (3% of GDP) and debt (60% of GDP); and in case of having a debt level above 60% it should each year decline with a satisfactory pace towards a level below. As outlined by the "preventive arm" regulation, all EU member states are each year obliged to submit a SGP compliance report for the scrutiny and evaluation of the European Commission and the Council of the European Union, that will present the country's expected fiscal development for the current and subsequent three years. These reports are called "stability programmes" for eurozone Member States and "convergence programmes" for non-eurozone Member States, but despite having different titles they are identical in regards of the content. After the reform of the SGP in 2005, these programmes have also included the Medium-Term budgetary Objectives (MTO's), being individually calculated for each Member State as the medium-term sustainable average-limit for the country's structural deficit, and the Member State is also obliged to outline the measures it intends to implement to attain its MTO. If the EU Member State does not comply with both the deficit limit and the debt limit, a so-called "Excessive Deficit Procedure" (EDP) is initiated along with a deadline to comply, which basically includes and outlines an "adjustment path towards reaching the MTO". This procedure is outlined by the "dissuasive arm" regulation.

The SGP was initially proposed by German finance minister Theo Waigel in the mid-1990s. Germany had long maintained a low-inflation policy, which had been an important part of the German economy's strong performance since the 1950s. The German government hoped to ensure the continuation of that policy through the SGP, which would ensure the prevalence of fiscal responsibility, and limit the ability of governments to exert inflationary pressures on the European economy. As such, it was also described to be a key tool for the Member States adopting the euro, to ensure that they did not only meet the Maastricht convergence criteria at the time of adopting the euro, but kept on to comply with the fiscal criteria for the following years.
