Birchills Junction (grid reference SK002000) is the canal junction at the northern limit of what is now called the Walsall Canal where it meets the Wyrley and Essington Canal main line, near Walsall, West Midlands, England. It opened in 1798, but lasted for little more than a year, until it was re-opened in 1841 when a connecting link was built to the Birmingham Canal Navigations' southern route to Walsall.
