Finland is the second largest oat producer in Europe. Despite the existing knowledge of phenolics in oat, there is little information on the phenolic composition of oats from Finland. The aim of the study was to investigate the concentrations of free and bound phenolic acids, as well as avenanthramides in eight Finnish cultivars of husked oat (<i>Avena sativa</i> L.). Seven phenolic acids and one phenolic aldehyde were identified, including, in decreasing order of abundance: <i>p</i>-coumaric, ferulic, cinnamic, syringic, vanillic, 2,4-dihydroxybenzoic, and <i>o</i>-coumaric acids and syringaldehyde. Phenolic acids were mostly found as bound compounds. Significant varietal differences (<i>p</i> < 0.05) were observed in the cumulative content of phenolic acids, with the lowest level found in cv. ‘Viviana’ (1202 ± 52.9 mg kg<sup>–1</sup>) and the highest in cv. ‘Akseli’ (1687 ± 80.2 mg kg<sup>–1</sup>). Avenanthramides (AVNs) 2a, 2p, and 2f were the most abundant. Total AVNs levels ranged from 26.7 ± 1.44 to 185 ± 12.5 mg kg<sup>–1</sup> in cv. ‘Avetron’ and ‘Viviana’, respectively
