Leith Street is a narrow road within the UNESCO World Heritage Site of the city of George Town within the Malaysian state of Penang.

During Leith's tenure, he succeeded in gaining a narrow hinterland on the Malay Peninsula directly opposite Penang Island from Kedah; the land was subsequently named Province Wellesley (now Seberang Perai).

[2] It was the first local authority to be founded in Malaya; the committee would gradually evolve over the centuries into the present-day Penang Island City Council.

When Leith Street was created in the early 19th century, the road was to be lined with palm trees, hence the Malay nickname Nyior Cabang.

Notably, Leith Street is also known as the place where the renowned shoemaker, Jimmy Choo, started making shoes as an apprentice.
