Windermere (/ˈwɪndərmɪər/) is a town in the civil parish of Windermere and Bowness, in the Westmorland and Furness district in the ceremonial county of Cumbria, England; it is within the Lake District National Park. The town lies about half a mile (1 km) east of the lake, Windermere, from which it takes its name. In 2021 it had a population of 4,826.

While Windermere town does not itself touch the lake, it forms one urban area with the older town of Bowness-on-Windermere, which is directly on the lake shore. Windermere began to grow when the railway station and hotel of the same name opened in 1847. Tourism is popular in the town, owing to its proximity to the lake and local scenery. Boats from the piers in Bowness sail around the lake, many calling at Ambleside or at Lakeside where there is a restored railway.

Historically a part of the county of Westmorland, Windermere town was known as Birthwaite prior to the arrival of the Kendal and Windermere Railway, which stimulated its development. Windermere station offers train and bus connections to the surrounding area, Manchester Airport and the West Coast Main Line.

The geological formations around the area take their name from the town. They are called the Windermere Group of sedimentary rocks.

The word "Windermere" is thought to translate as "Winand or Vinand's lake". The specific has usually been identified with an Old Swedish personal name Vinandr. The other possibility is for a Continental Germanic name Wīnand. The second element is Old English 'mere', meaning 'lake' or 'pool'. There is a reference to "Wynandermer" in 1396.

Windermere was from 1894 to 1974 governed by an urban district council which in 1905 absorbed the former Bowness-on-Windermere UDC although Bowness remained a separate civil parish until 1974. Windermere UDC had slight boundary changes in 1934 and was abolished by the Local Government Act 1972 replacing it with South Lakeland District Council. On 29 July 2020 the merged parish was renamed from "Windermere" to "Windermere and Bowness". In 2023 South Lakeland was abolished and merged into Westmorland and Furness unitary authority area.

Windermere railway station was built in 1847 and was the reason the town was established. The station serves trains run by Northern to Oxenholme on the West Coast Main Line; some services continue on to Manchester Airport.

Stagecoach Cumbria operates bus routes to Keswick, Kendal, Lancaster, Grasmere, Ambleside, Bowness-on-Windermere, Barrow-in-Furness, Penrith and Coniston.

The town is near the A591 road, a major road which runs through the Lake District from Kendal to Keswick.
