Lockerbie Square Historic District is a national historic district on the National Register of Historic Places within Indianapolis, Indiana, listed on February 23, 1973, with a boundary increase on July 28, 1987. It is noted for its Federal, Italianate, and Queen Anne style architecture. The original platting of Lockerbie Square, done by Jannett Smith Lockerbie McOuat and named for her father, Scottish immigrant George Murray Lockerbie, was between 1847 and 1850. The 1960s saw an immense effort to save the buildings within the district, becoming the first historic district in Indianapolis. Many of the buildings date from 1855 to 1930. James Whitcomb Riley, famed Hoosier poet, lived in the district for over two decades. He was known to give candy to local children on his regular walks.
