अर्थशास्त्र में, सेवा (Service) एक ऐसा लेनदेन है जिसमें विक्रेता से खरीदार को कोई भौतिक सामान स्थानांतरित नहीं किया जाता। इस तरह की सेवा का लाभ विनिमय करने के लिए खरीदार की इच्छा द्वारा प्रदर्शित होता है। सार्वजनिक सेवाएं वे हैं जिनके लिए पूरा समाज (राष्ट्र राज्य, वित्तीय संघ या क्षेत्र) भुगतान करता हैं। संसाधनों, कौशल, सरलता और अनुभव का उपयोग करते हुए, सेवा उपभोक्ताओं सेवा प्रदाता लाभ प्रदान करते हैं। सेवा अमूर्त प्रकृत का है।
