Cavan Road is a minor road in the Lavender subzone of Kallang, Singapore. The road connects Lavender Street to Horne Road. According to Singapore Street Names1, the road was named after the 10th Earl of Cavan, Frederick Rudolph Lambert (1865-1946), who was a Field Marshall in the First World War.
Although he has no connection to Singapore whatsoever, he was one of the First World War generals and admirals which the British government in Singapore honoured with road names.
