Alaba-Kʼabeena (Alaaba, Alaba, Allaaba, Halaba), also known as Wanbasana, is a Highland East Cushitic language spoken in Ethiopia by the Halaba and Kebena people in the Great Rift Valley southwest of Lake Shala, specifically in Alaba special district, the Kebena district of Gurage Zone, and the Goro district of Oromia Region. The literacy rate of native speakers in their language is below 1%, while their literacy rate in second languages is 8.6%; Alaba-Kʼabeena is taught in primary schools. It has an 81% lexical similarity with Kambaata. However, Fleming (1976) classifies Kʼabeena (also transliterated "Qebena" or "Kebena") as a dialect of Kambaata, and Blench (2006) classifies both as dialects of Kambaata. The 2007 census in Ethiopia lists Alaba and Qebena as separate languages.

A collection of over 400 proverbs in this language has been published with English translations.

The Alaba speakers consists of 23 different groups.

The number of speakers of this language has increased. In 2001 there were 204,000 speakers and in 2007 approximately 280,000 speakers.

Alaba has ten vowels, which contrast in height and backness as well as in length.

In linguistics, the term refers to the duplication of sounds or words as well as the associated linguistic phenomena, such as a longer pronunciation.

This denotes a doubled of sounds in the pronunciation of the word. Almost all consonants have a geminated counterpart. This means, in terms of stops, that the release is being delayed while other consonants are being extended. Similarities to the Shaddah and its function in Arabic are visible.

Geminates in Alaba are often used to indicate the plural form.
