Lalitpur Metropolitan City (Nepali: ललितपुर महानगरपालिका, Lālitapura Mahānagarapālikā), also known as Patan (Sanskrit: पाटन, Pāṭana), Yala (Newar: 𑐫𑐮), and Manigal, is a metropolitan city and fourth most populous city of Nepal with 299,843 inhabitants living in 49,044 households per the 2021 census. It is located in the south-central part of Kathmandu Valley, a large valley in the high plateaus in central Nepal, at an altitude of 1,400 metres (4,600 feet).

It is best known for its rich cultural heritage, particularly its tradition of arts and crafts. It has a multi-ethnic population with a Hindu and Buddhist majority. Religious and cultural festivities form a major part of the lives of people residing in Kathmandu. Tourism is an important part of the city's economy and it is renowned for its festivals and feasts, ancient art, and the making of metallic, wood and stone statues. Lalitpur is also home to Patan Durbar Square, which has been listed by UNESCO as a World Heritage Site.

One of the most used and typical Newar names of Lalitpur is Yala. It is said that King Yalamber or Yellung Hang named this city after himself, and ever since this ancient city was known as Yala. There are many legends about its name. The most popular one is the legend of the god Rato Machhindranath (also known as Bunga Dyah), who was brought to the valley from Kamaru Kamachhya, located in Assam, India, by a group of three people representing the three kingdoms centered in the Kathmandu Valley. One of them was called Lalit, a farmer who carried god Rato Machhindranath to the valley all the way from Assam, India. The purpose of bringing the god Rato Machhindranath to the valley was to overcome the worst drought there. There was a strong belief that the god Rato Machhindranath would bring rain in the valley. It was due to Lalit's effort that the god Rato Machhindranath was settled in Lalitpur. Many believe that the name of the town is kept after his name Lalit and pur meaning township.

In May, a chariot festival honoring the deity known as Bunga Dyah Jatra is held in Patan. It is the longest and one of the most important religious celebrations in Patan. During the month-long festival, an idol of Rato Machhendanath is placed on a tall chariot and pulled through the city streets in stages.

Lalitpur is believed to have been founded in 249 BC by the Emperor Ashoka. It was further expanded by the Mallas during the medieval period.

Later Lalitpur is said to have been re-established by King Veer Deva in 299 AD, but there is unanimity among scholars that Patan was a well established and developed town since ancient times. Several historical records including many other legends indicate that Patan is the oldest of all the cities of Kathmandu Valley. According to a very old Kirat chronicle, Patan was founded by Kirat rulers long before the Licchavi rulers came into the political scene in Kathmandu Valley. According to that chronicle, the earliest known capital of Kirat rulers was Thankot. Kathmandu, the present capital was most possibly removed from Thankot to Patan after the Kirati King Yalamber came into power sometimes around second century AD.

The Licchavi era was followed by the Malla era. Rulers from Tirhut, upon being attacked by the Delhi Sultanate, fled north to the Kathmandu valley. They intermarried with Nepali royalty, and this led to the Malla era. The early years of the Malla era were turbulent, with raids and attacks from Khas and Turk Muslims. There was also a devastating earthquake which claimed the lives of a third of Kathmandu's population, including the king Abhaya Malla. These disasters led to the destruction of most of the architecture of the Licchavi era (such as Mangriha and Kailashkut Bhawan), and the loss of literature collected in various monasteries within the city. Despite the initial hardships, Kathmandu rose to prominence again and, during most of the Malla era, dominated the trade between India and Tibet. Nepali currency became the standard currency in trans-Himalayan trade.

During the later part of the Malla era, Kathmandu Valley comprised four fortified cities: Kantipur, Lalitpur, Bhaktapur, and Kirtipur. These served as the capitals of the Malla confederation of Nepal. These states competed with each other in the arts, architecture, esthetics, and trade, resulting in tremendous development. The kings of this period directly influenced or involved themselves in the construction of public buildings, squares, and temples, as well as the development of waterspouts, the institutionalisation of trusts (called guthis), the codification of laws, the writing of dramas, and the performance of plays in city squares. Evidence of an influx of ideas from India, Tibet, China, Persia, and Europe among other places can be found in a stone inscription from the time of king Pratap Malla. Books have been found from this era that describe their tantric tradition (e.g. Tantrakhyan), medicine (e.g. Haramekhala), religion (e.g. Mooldevshashidev), law, morals, and history. Amarkosh, a Sanskrit-Nepal Bhasa dictionary from 1381 AD, was also found. Architecturally notable buildings from this era include Kathmandu Durbar Square, Patan Durbar Square, Bhaktapur Durbar Square, the former durbar of Kirtipur, Nyatapola, Kumbheshwar, the Krishna temple, and others.

In 1768, Lalitpur was annexed to the Gorkha Kingdom by Prithvi Narayan Shah without any battle.

Lalitpur is on the elevated tract of land in Kathmandu Valley on the south side of the Bagmati River, which separates it from the city of Kathmandu on the northern and western side. The Karmanasa Khola acts as the boundary on the eastern side. It was developed on relatively thin layers of deposited clay and gravel in the central part of a dried ancient lake known as the Nagdaha. The city has an area of 15.43 square kilometres and is divided into 29 municipal wards.

Climate is characterized by relatively high temperatures and evenly distributed precipitation throughout the year. The Köppen Climate Classification subtype for this climate is "Cfa" (Humid Subtropical Climate).

The city was initially designed in the shape of the Buddhist Dharma-Chakra (Wheel of Righteousness). The four thurs or mounds on the perimeter of Patan are ascribed around, one at each corner of its cardinal points, which are popularly known as Asoka Stupas. Legend has it that Emperor Asoka (the legendary King of India) visited with his daughter Charumati to Kathmandu in 250 BC and erected five Asoka Stupas, four in the surrounding and one at the middle of the Patan. The size and shape of these stupas seem to breathe their antiquity in a real sense. There are more than 1,200 Buddhist monuments of various shapes and sizes scattered in and around the city.

The most important monument of the city is Patan Durbar Square, which has been listed by UNESCO as one of seven Monument Zones that make up the Kathmandu Valley World Heritage Site. The seven monument zones were included in the World Heritage List in 1979 as one integrated site. The monument zones are declared as protected and preserved according to the Monuments Preservation Act of 1956. The Square was heavily damaged on 25 April 2015 by an earthquake.

Lalitpur was planned in Vihars and Bahils. Out of 295 Vihars and Bahils of the valley 56% of them are in Patan. The water conduits, stone spouts, jaladroni (water tanks), artistic gate ways, Hindu temples and Buddhist Vihars adorn the city.
