Lamu County is a county in Kenya located along the North Coast of the country and is one of the six Coastal Counties in Kenya. Its capital is the town of Lamu. It borders Tana River County to the southwest, Garissa County to the north, Somalia to the northeast, and the Indian Ocean to the South. It is the Smallest County in Kenya by population.

The county has a land surface of 6,273.1 km (2,422.1 sq mi), including the mainland and over 65 islands that form the Lamu Archipelago. The total length of the coastline is 130 km (81 mi), while the land water mass area stands at 308 km (119 sq mi).

The county is made of a cosmopolitan population composed of communities such as Aweer, Oromo,Somalis, Swahilis, Arabs, Kore, Kikuyu, and other migrant communities from all over the country. The county had a total population of 143,920 of which 76,103 were males 67,813 females and 4 intersex persons during the 2019 census of Kenya. There were 37,963 households with an average household size of 3.7 persons per household and a population density of 23 people per square kilometre.

The LAPSSET project is expected to attract a huge migrant population estimated to be over one million people. This will certainly overstretch the county's social services necessitating commensurate development planning for adequate service provision.

Lamu town is termed as "the oldest and best-preserved Swahili settlement in East Africa” but neighboring islands also have numerous archaeological remnants of history dating as far back as the 14th Century.

Among the challenges facing Lamu is population growth owing to migration into Lamu from other parts of the country, fueled partly by the anticipated opportunities accruing from the Lamu Port South Sudan-Ethiopia Transport (LAPSSET) Corridor. Other challenges include landlessness and poor land management, insufficient social services such as healthcare and education, inadequate supply of piped and fresh water, under-developed infrastructure, and food insecurity.
