James Thompson appeals the district court’s 1 dismissal of his 42 U.S.C. § 1983 action seeking damages for the removal of his automobiles from land that he leased. Following careful review of the record, we find that Thompson’s notice of appeal (NOA) was untimely by one day because he filed it on May 23, thirty-one days after the district court entered judgment on April 22, 2014, and the thirtieth day did not fall on a Saturday, Sunday, or legal holiday. See Fed.R.App. P. 4(a)(1) (NOA must be filed within 30 days after entry of judgment); Fed.R.App. P. 26(a) (computation of time); Dieser v. Cont’l Cas. Co., 440 F.3d 920, 923 (8th Cir. 2006) (timely NOA is mandatory and jurisdictional; court will raise jurisdictional issues sua sponte). Accordingly, we dismiss the appeal for lack of jurisdiction.
